I am closing this as a duplicate of your own topic.
The Wishlist category has a rule that you cannot have duplicates in it:
If you cannot locate your old post, you can search for all of your posts in a category by putting an @ sign in front of your name. For example: @CatchySwing5372 #self-service:wishlist. (This topic will no longer appear in search results, though, as it is being unlisted.)
