Tab buttons not aligning right

[Prefader]

Man, I know this has gone offtopic from the thread title, but I've given up on the tabs for the time being.

The spinner - are you sure I had that "packlocation" syntax backwards? Swapping them doesn't do the trick - I thought it was "horizontal,vertical". Do any up-to-date interfaces have spinners at the top of the hotkey window? I'll post pictures of what's happening when I get a chance.

Edit - Talyns! thank you! Whatever you did appears to have worked! Was it the text in the tab buttons?
