The addon will never show as current now, and sites like curse won't mark it as tbc compat, or as classic compat if there's no classic toc...

I haven't seen this issue, I assume it's been fixed. Please re-open this if you are still getting this error. Thanks!

It was actually deleted because curse was rejecting it. I'm unsure if they have an error on their site or what. But I believe these sites are reading the ToC for the version number and using that to list it as a TBC addon. It is properly showing up under TBC.
