How is effect presets supposed to work

I get nothing useful done there - I can only press diskette button and save, but not give names, or rename or organize in any way.
 
EDIT: Double-click on NoPreset text and you can edit.
Thought I tried that, but obviously not.
 
I now have plenty plugins with like 10 blank rows in the list, that I cannot select or delete.
Also checkmarks on two first etc.
 
How do I get rid of this and clean up?
No idea what happend.
 
 
Thanks.

Thanks.
VST3 stuff seems to list present internal presets to some degree, then ability to add your own.
Waves stuff list loads of presets - but you loose categories in Waves own menu system.
But many plugins start with an empty list of 10 lines, then a separator, and what you saved.
And others when you enter one saved preset - you get three lines with the same name, and all checked.
And other cases you get a checkmark at one of the empty lines in list, then 9 blank lines.
 
I wonder if all is as planned here?
A mockup between what VST2 and VST3 do, or something?
List in Synth rack was more compact, only your own saved ones.
So plugin property page is where there seems to be a mix of fixed and own presets.

 
Is there a way to get rid of these empty blank lines?
