Number of Advised Staff Changing

In the 'BOARD' window, bottom left section 'STAFF' the number of staff I am Advised I can have changes occassionally of it's own accord throughout a playing season. Currently I am a month away from the end of season and the number of first team coaches advised has changed from 6 to 5 and the board keep telling me I am overstaffed. Does anybody know of any particular reason for this or is it a bug in FM2018?

The board very often increases the number of staff that you are allowed to employ when the team is exceeding expectations and / or when you gain promotion. If the board has reduced the number of advised staff I guess that it is is not happy with the progress that your team is achieving.

I've just won Serie A with Parma and we're in the Italian Cup final so they should be happy!!

In that case I've no idea - maybe the are just trying to save money.
