Can't unlock trophy for completing ghalts lore

before he update that changed everyone’s lore completion requirements, I had gotten all of ghalts lore done and only needed 8 out of the 10 first strikes in pvp. When the update came and he only required 1 first strike it unlocked the master of ghalt title but didn’t unlock the trophy. I had played multiple matches and even got another first strike in pvp and I still cannot unlock the trophy. Has this happened to anyone else?
