Being able to distinguish them at least would help.

That value is suspiciously low, you might want to double-check you're
setting the correct RX timestamp in the driver, mac80211 expects the
timestamp to be at the first symbol of the frame.

Ok so at least it's not trying to remove the same STA twice :)
