Wrong team's jerseys in the stands

I'm playing a custom franchise league as TPS (Turku) and during playoffs the stands are full of Tappara's (Tampere) jerseys. Even though they aren't even in the playoffs. What makes this worse is that there is a long rivalry between Turku and Tampere. Small thing but very annoying that there's next to none TPS fans in the stands while playing for the cup. There's four TPS jerseys visible in the screenshot so it's not like the game thinks Tappara is playing.

Also I had to make a whole new Franchise because my old one with a similar setting and the same jersey issue got stuck in the year 2036 start of the season, and wouldn't sim to the start of pre-season.
