Trick or Treat in MUT broken

This is the second time I’ve played through 3 games on the first level, and started the second level, but it locks after I win 2 games on the second level - grimhollow lane. So twice I haven’t even been able to access the 3rd game on level 2. It claims I don’t have the access key but I used it already to play the first 2 games so see the issue? With so many rewards tied to these events this needs to be fixed.
