Customized Card selections are not sticking, what happened, how can I fix it?

[Sarah Lynch]

Yesterday, December 20th, all of my kanban cards that I had customized with pertinent information were gone. All the selections I made have disappeared from all of my project boards.

I re-selected the customized fields that I want to see on the cards and it only stayed for the one project board I did this on versus the 500 + projects I have set up. Whereas before the 20th I could see this selection on everyone.

Does anyone know what happened and how I can fix it?
