Came here to report the same issue.
The game only allows for 3 substitutions to be made in the dutch second division.
This should currently be 5 substitutions as the rules have been (temporarily) changed.
I am experiencing the same issue in the KNVB Beker: only 3 subs there when IRL it has been increased to 5
