What is wrong with "be there or be square" challange?

Its simple challange, req to gather two invitations.
I just did it. Endgame screen said i did it, but then in tome menu, it says that i have to get two invitations…
Is there something i dont know? Is it a bug? Can someone confirm its not only me?

  • I have had issues on various challenges where the progress counts up in the trial, but seems to reset at the end, though they have actually been counted and been carried over/been completed.

    Check the actual tome to see if it's actually done.
