7 sub glitch

So I'm playing FC 26 on my Switch. And I have two career mode saves, Liverpool and Sunderland. The latter has 9 subs in my team, but my Liverpool career mode only has 7, so I don't know how and why this is happening. I do have a few theories, so plz upvote this and reply to help. Even still, this bug should've been resolved:

A: I'm playing this on my Switch 1, not Switch 2, so the generation downgrade might be a factor

B: The dates of the 2 saves (which I'll put screenshots of evidence) are 9 days apart, so an upgrade might've happened in that time, but still it shouldn't bug out
