No longer showing users enrolled via category enrolments

[cbrherms]

We currently make use of category enrolments to give Heads of School and Programme Leaders access to each of their courses/modules.
School -> Course ->Academic Year -> Modules

On the previous version when we were running 3.7 we were able to show these HoS / PL roles within the course contacts block but this now no longer appears to be the case.
If we were to to manually assign this role then that user would appear in the block, but this is not possible when that role is already assigned via another enrolment method.

Would it be possible to make it so this also pays attention to other types of enrolment?
