Hello,
I've seen the same thing. I'm not sure when it started, but it may have been when I upgraded from 2.4 to 2.6
I am now setting up an entirely new 2.8 instance, on a new VM, and the problem persists. The log file seems to know exactly when the enrollments ran, but the users list is wrong:
From the log file on one of the courses:
"23 Apr, 15:45" Admin User Ben Course: CHEMH111A03.F15 - Chemical Structure and Bonding System User unenrolment updated The user with id '2' updated the enrolment for the user with id '1855' using the enrolment method 'flatfile' in the course with id '503'. cli
"23 Apr, 15:45" Admin User Louise Course: CHEMH111A03.F15 - Chemical Structure and Bonding System User unenrolment updated The user with id '2' updated the enrolment for the user with id '1086' using the enrolment method 'flatfile' in the course with id '503'. cli
