Squad sizes exceed 150 people

I edited the database (see below) and within 10 years of DB testing the total squad size for each team is over 150 for all 10 teams. Upon checking EPL clubs their total squad size is around 50. Is there a fix to this?

Quick details - Created a nation (used CIS), competition, cities, stadiums and clubs (10). Set up nation rules including a reserve and U19 comp. Included max squad size of 23 (I understand that this is for senior squad only)

Also I set teams to have a sugar daddy (underwriter) and included increase starting funds. Also within 10 years 3 teams turned semi pro but from the other 7, 3 of those have negative balances. Is there something to help this?

Playing around with finances makes teams turn professional too quickly and go into a negative balance within 5 years.

Any help to my 2 questions would be greatly appreciated.
