Hi.
Yes I checked this. Moodle docs has a list of permission dependencies for this plug-in ... they are all set.
I have also run the maintenance cron script just in case.
None of my courses have the facility to add enrolment method ... as teacher, creator or manager ... yet all show the listed permissions as granted.
My Moodle version is 3.4.3+ (build 20180614) ... with no possibility of updating ...; but then I do not believe that this particular area has changed with more recent builds.
