Custom Options Disappearing Even Though They’re Working

I have a rather strange problem and I’ve read and read through these support forum posts to try to find if anyone else has had the problem but it’s not quite the same as anyone else.

All of my custom options I put in myself have disappeared from the Adminimize settings so that I cannot check or uncheck them. However, they all seem to still be working on the site. I cannot remove them or change them, but they are still somehow working.

I noticed this because I actually need to change the appearance of one of them but I cannot because it’s not showing up in the user interface.

I thought maybe it was a max_input_vars problem, but I tried that and increased it all the way up to 9000 and they still won’t show up again. Anyone have any idea what is causing this and how to fix it?
