Selection bug - extra clips selected even when lasso doesn't touch them

If I am careful to select just one clip, that clip is selected correctly. But if the lasso touches the track folder bar just above that clip, it seems to select a bunch of other clips in that same track.
 

 
It doesn't select all clips - just ones within some arbitrary set of bounds that I can't work out. Here's a different example: same project, different tracks and track folder.
 

 
As you can imagine, this makes a lot of selection tasks very difficult, and the act of cutting out an section of a song (eg. a verse or a chorus) almost impossible. The only way to do it is to manually select each of the clips one by one, which is ridiculous.
 
This seems completely counterintuitive and harmful to workflow - does anybody know what's going on here?

Anybody? Is this user error? Or a bug? It's ruining my workflow.

I want to be able to select a whole rectangular area of clips. Selecting them individually takes a long time.

You're left-dragging to select, whereas I'm right-dragging. If I left-drag then that's annoying in a different way because that'll leave out anything I've not entirely selected - so if one of the clips I wanted happened to start outside the bounds of my selection, I have to stop and redo it.
Here's the documentation on selecting clips: http://www.cakewalk.com/Documentation?product=SONAR%20X3&language=3&help=Arranging.15.html
I'm using approach 2: "Select several clips at once - With the right mouse button, drag in a rectangular pattern that touches each clip." Obviously it has a rather liberal idea of which clips are the 'several' I might want to select.
Note that there is no documentation there for dragging with the left mouse button! This allows it an even more liberal notion, no doubt...
 
I'd be happy for it to select an entire clip even when I just touch part of it - it's the selection of seemingly-unrelated clips either side that completely stops me doing what I want to do (ie. cut and paste sections of songs) without laboriously selecting each individual clip one by one.

@OP - what version of Sonar please?
Thanks..

I reproduced this behavior in Platinum.
 
The problem is not with the lasso, but with folders and how the clips are split.
 
Notice in the OP's example 2 that the split between Record 22 and Record 31 is not labeled in the folder.  This means that the folder does not recognize the split even though there is a separation line showing in the folder.  When you lasso into the folder, the folder thinks the two clips are not split and selects them both.
 
Whenever you make a split with the Split tool or "S" key, the parent folder shows the split and labels the new split with the folder name.
 
Splits made with the Comp tool in take lanes, however, do not appear to label the split in the folder track and will create the reported behavior.
 
I'm not sure if this is a defect or working as intended, but hope that this clarifies that the problem lies with the folders and the method that is used for splitting clips, not the lasso.

Glad my explanation was clear enough to understand.
 
The confusing thing is the split bars displaying, but not the labels.
 
I tried recording 2 overlapping takes in Platinum and just like your examples, I ended up with 2 separate clips, but only 1 label in the track folder.
