Most of my courses are set to "separate groups" and I have turned on the "groupings" options as I want to make activities available (and viewable) to specific groups only. This works fine until students click on their gradebook. In their user report, all activities are shown (and that's a lot as I use Moodle as my main gradebook, and there are 2 teachers in the same course who do the same...), even the ones which have been set to be viewable only by members of other groupings. If a student clicks on an activity that they're not supposed to see (i.e. an activity set to be viewable only by members of another grouping), they get an error message. So basically, a student might end up with dozens of rows completely irrelevant to them with no grades in it. It is quite confusing.

It would be great if activities that should not be viewed by specific groupings were not shown in the user gradebook. This is possible and works well with activities which are set to "hide". Is there any chance to get this to work for groupings as well? Would it be possible for activities set to specific groupings to get a similar "hide" setting?

I work in a K-12 and students (and some teachers) are really confused by this little bug.

I hope the explanation is clear enough, if it isn't, please let me know and I'll try to clarify.
