I've beat my head against this concrete wall long enough - anyone seen anything like this before?

I have 2 new users. They both created new projects and ran them.

One user can see everything in the job log and when they refresh after changing the check boxes, all the items they checked from the log show up as you would expect.

The other user can see a tiny fraction of the job log - about 20 lines out of 300+. No matter what they set, the highest number they see is about 20 lines. In fact, only lines from Set, Env, MkDir, and Exec ever show up, but never all of the lines for each of those types. They can set or clear all the other check boxes, and there is no change to the displayed lines on refresh. If they uncheck Env, for example, all the Env lines disappear on refresh, and then the same few show up when they recheck the Env box and refresh.

I have verified these users are all in the same security groups and have the same permissions. Repeated runs with different security groups don't show up anything different - these same two users get this oddly hodge-podge set of job log entries no matter what groups they are running under. I can sign in as root and see all the lines are in the log, the users just can't see them.

Anyone seen anything remotely similar? I'm baffled!
