NTBSS: Master Character Training Pack - Mei Terumi

I own the second season pass and downloaded this but I can't train under her. I also went to the inn and redemmed it, but it isn't working. Please help

U guys are idiots when you buy a dlc u have to get it from the gift shop from the inn

I purchased this with the season pass; it downloaded but I can't use it. It tells me to rebuy it, but then that I already own it. I want a refund.
