I just noticed that there's a new message, log-action-filter-growthexperiments-claimmentee. However, claimmentee aren't mentee-requested claims; the mentee doesn't need to interact with them in any way. This message sounds to me like it's that way.
What about changing log-action-filter-growthexperiments-claimmentee to "Mentee claims" (or "Claiming mentees") and changing log-action-filter-growthexperiments-setmentor to "Setting mentor", to make the actual difference clearer?
