SW not allowing me to edit a simple bend

Hi all,

I have a very simple piece that I am holding in my hand and realized the little tabs are the wrong length.  So I went into try to tweak them and found that SW2013 would not allow me to edit the flange length.  I mean, I can punch a new number in there but it wont save it.  I open the feature again and it is the same wrong number.  This is happening on both tabs.

Any thoughts?
