Not getting crew challenge rewards

Haven’t seen anyone else posting about this but I seem to be not receiving my crew challenge rewards from the DLC.

Have played DLC1 and DLC2.
On DLC1: I found all the holojack and clicked to hear them but never received the mail containing the holojack room decoration
On DLC2: I found all the wedding gifts but never received the mail from Gaige with the JUST MARRIED Poster

Additional context: Played the game entirely through split-screen co-op. Both of our challenges marked as complete and she received the two mails & room decos in question.

Has anyone else encountered this? Is there anything I can do to fix this?
