Using Curve 9320 with latest O/S

OK, I've the "Speed Dial Numbers" list on BB (press call button then BB key, View --> Speed Dial List"

If I go to one that's used which I don't want, I press BB key, then select delete . Get "Remove Item from List?" Yes/No

I select yes, but item is not deleted!

If I try to move an item, I can move it up/down list but I cannot lock it to a new letter/number.

Any ideas?

I don't see what I;m doing wrong, looks like some sort of bug

Update: Removing battery to reset phone.
