Home Grown Not Working

So, managing Barca, it's 2022, I signed Hector Bellerin, Dani Olmo and Alex Grimaldo to bulk up my home grown players. I go to register for the Champions League. I click on the screen to register the squad, under "Home-Grown Status" column they are marked "Trained at Club (0-21)" because they came through the Barca youth system. But then on the "Inf" column they do not have the blue "HGC" for them to count towards the champions league home grown allocation. Is this a bug?

When I started the game I knocked off the use of in-game editor. Does anybody know how I can fix this because it is ruining my game? Very annoying.

They may have been trained by club but they are not home grown by club by UEFA's rules. See here for rule. They need to be at the club for at least three years between the ages of fifteen and twenty-one to be HGC. Bellerin left for Arsenal in 2011 when he was 16, so only spent one year. Olmo left for Zagreb in 2014 when he was 16, so again only one year. As for Grimaldo, I'm not too sure. My guess would be that because he was a Barcelona B player from the age of 16 to 20 (then left to Benfica), he wasn't technically a 'Barcelona' player as such, but I could be wrong on that one for Grimaldo.
