Ultimate Branding Admin Bar not appearing and input area messed up styling

Ultimate Branding "Admin Bar" used to work, had it deactivated for quite some time, now reactivated and doesn't work correctly: 1) it doesn't show up in the WP Admin Bar, 2) its input field has odd styling

I removed 2 old custom links and added 1 new one.

Upon saving, the Admin Bar settings looked like the attached screenshot (but I didn't see any JS errors in Chrome Inspector Console).

Any ideas?
