Wishlist not syncing?

This has been going on for several days. I removed a game from my Steam wishlist that I decided I didn't want. It still shows up as wishlsted on Steamgifts at
https://www.steamgifts.com/giveaways/search?type=wishlist and https://www.steamgifts.com/account/steam/wishlist

I have synced my account on Steamgifts with my account on Steam more than once each day the last several days, and Steamgifts says the account was synced every time. But the game won't go away from my wishlist here. I also don't think new games I add to the wishlist on Steam are showing up here.

Any ideas what's going on or what to do about it?

My Steam is set to public for all options. I have also tried using ctrl+F5 to hard refresh the wishlist giveaways page and it didn't affect anything.
