iOS Question Bug clicking "font" on textview resets the screen

I'm not sure that I understand. TextView doesn't show any arrow.

In the designer
click on textview
scroll down to "Font"
(there is a small arrow, if you click it , it opens the options for fonts.)
when you click it...the textview options jump to the top. This is the little window in the designer.
when you scroll down again and click "Fonts" small arrow ... it works normally.
takes alot of time each time you change the options for textview to keep having the scrolling down.

Seems to work fine here. I'm using a more recent version of properties grid control so it might have been fixed.
