Idk if this is happening for anyone else, but I can't check or uncheck achievements to save them. I'll click the box, and it will just bring me to the single achievement but not let me toggle.

Yeah, I think it's because the link coding isn't closed until after the checkbox (at least in the few I looked at), so it's part of the link as well.

Also came to report this problem. Still not working ;D

edit: Still having this issue 16th March The checkbox is included in the achievement link of the achievement title next to it, so it can't be toggled.
