Wrong gamer tag, after an EASHL game completion.

I've noticed it in NHL 24 where, even though I started the EASHL 6vs6 game with my correct gamer tag, the end result regardless of either a win or a loss, my gamer tag would be something different in the player summary and finding teammates/opponents lobby. It was more common if I had a couple of losses straight, and then have an unusually decent game to help my teammates win the game: yes, I play as the goalie. 

And it isn't just a win. It's almost as if I was allowed to actually be in the right spot, at the right time, and positively contribute to my team's success. The previous couple of games, I couldn't stop a beach ball, gave up 9 goals (average), still make 20 saves or more, etc. Then, miraculously, I'm actually allowed to play. Oh, wait, "Dirty5hole" is now your gamer tag, despite it not actually being your gamer tag. By the way, this gamer tag is what I've most recently experienced, in NHL 25, on PS5. 

Does anyone else experience this whilst playing online, with either console?
