Step sequencer velocity bars don't line up with hits when "Fit To Quarters" is on

As a rule I don't use the step sequencer much because the last time I tried to make serious use of it I found it problematic to say the least. But tonight I decided I'd have another try, and immediately ran up against something frustrating which may or not be a bug, or maybe just I'm misunderstanding how things work. Here goes:
 
When "Fit To Quarters" is turned on, the velocity bars don't line up properly with the notes in the sequencer. Here's a graphic example:
 

 
Here you can see I have a drum sounding on every beat. But the velocity bars seem to be following their own scale. For the life of me I cannot think of a way in which this would be expected behavior. 
 
If I then turn "Fit To Quarters" off, nothing immediately happens. BUT...if I then enter another note into that row, they immediately jump into the correct slots:
 

 
Have I found yet another stupid, sloppy bug, or is it that I'm completely mistaken and things are working as expected (which is how my "bug findings" usually turn out lol)
 

Is the number of quarters set to less than the number of beats?  
 
I was able to get similar behavior with 8 beats with a fit to 4 quarters.  However, that's a weird response to a weird request.
 
Honestly, I don't quite get what the point of 'fit to quarters' is.  I read the fine manual and I still am baffled as to why it is even an option.

To tell you the truth Andy I don't really understand Fit To Quarters either. I understand that it's something I need to turn on if for instance I'm working in 6/8 and I want each step to represent a certain length. But I don't know enough to work out how to dial that in - I just play with it until it works 
 
Anyway I'm going to file a bug report. 

According to the online documentation: "Fit to Quarters will force the pattern duration to fit the specified number of quarter notes."

I suppose it may be useful for fitting an odd number of beats into an otherwise standard clip length.   Now I'm curious...  OP issue aside, of course. 
 

Right....  so if I have a clip duration of 7, and fit to say 3 quarter notes, I should effectively have an odd sounding result.
