Glitches in the Controls Library


There are glitches in the Controls Library that make it hard to use, for instance:

Here it seems impossible to fill  the Edit control up to the available area. As ListView is made of Edit controls the same glitch appears there . Note the area is extended but not fully.

Modifying the Edit contriol Width attribute will not do any better.  There are others glitches that limit access to  Font attributes I noticed. 

All these are rendering the main control pretty hard to reuse. Any idea to fix this? 
I mightt go back to MS as welll if it can't be fixed, it is very annoying to use a tool that in the end prooves broken.
I really don't want to repeat situations where he breaks down at the most inopportune moment
