At that time the DT1/DT2 "badges" used to show current status (not the status as of the time of the event). In other words, The Pharmacist was probably in DT1 at the time then this happened, so the event got captured, he later dropped out of DT1 (due to random selection I guess?) and his "badge" got updated to DT2.

Since the beginning of February we changed the logic a little bit so the "badges" now show the status as of the time of the event (i.e. you can see how the particular inclusion/exclusion affects the target user). It also "froze" old data so The Pharmacist's "badge" on that old record remains DT2 even though he's now DT1.

I have a plan to fix the historic data so that it makes more sense but that's a low priority, because that log is useful mostly in the current week before LoyceV's lists get updated.
