I'm having a similar issue with a new save, not from FM23, tons of money available for paying salaries and I can't even sign my best youth academy players, look at the tiny amount of money I am allowed to offer to each role in the last column
The only explanation I can find is that I don't have a lot of money in the bank, but I still find this annoyingly unfair, and I understand this is a bug:
i even sold a next transfer option for 600k (my balance was close to 0 at that moment) but still the same issue with salaries, please advise.
I forgot to mention this is also spanish league, 2nd division.
