I think I have a similar problem with my addon "Plates Of Awesome". Curseforge says "Last Released File:3 hours ago", so it recognized that file.
On curse itself the project seems to be marked as experimental, because it can not be found by the search function and no files show up there. Can you have a look into it?
Edit: Got it resolved, I just had to upload one file with release-flag and now it is working correctly.
