Semi-professional club can suddenly only offer amateur contract to staff. Why?

[Melon Lord]

Hey guys. So I'm managing a semi-professional club and have players and staff on part-time contracts but all of the sudden I can only offer amateur contracts to my staff with the exception of my scouts and assistant manager. Does anybody know the reason for this? How do I fix it?
I've attached some images just for clarity but I'll answer any questions to get this sorted.

Apologies if this has been posted about before but I tried searching and didn't find anything relevant.
Thanks in advance
