Disappearing Buttons

[Unikrom]

I'm running the stock standard UI and any buttons I add to my bar keep disappearing. I'm talking like making a Tracking button or Foraging. I'll make the button and add it to my bar then when I zone the buttons are gone and I have to re-add them. Whats worse is if I log I have to re-create the buttons and then add them as well. I've tried running the game as an admin and even completely re-installing the game to no avail.

Anyone know how to fix this?
