Nation Rules Error

[murphbot1204]

Hello,

I just converted a basic rules package into an advanced one, but when I try to test it, I keep getting this error

For clarity, I have checked. There are promotion/relegation rules in place for both divisions (2 up. 2 down, going to correct division, etc), and both leagues and parent comps use the Flexible Format Rules. Has anyone else had this issue and would be able to help?

i would say redo the Munster League or use Timo Irish database on FM22 to see his format because I had the same issue with the Northern Ireland database
