各自 totally broke my phase 2 kanji spreadsheet today

Im at exactly 412 hours of active immersion (Phase 2, Block B) and I just saw 各自 on a notice. My spreadsheet has this categorized strictly under N3 administrative nouns, but the context looked way too casual. I have a 30-second-per-card review limit and this completely ruined my morning metrics. If 各自 is used like this, is my classification formula off? How do I log this without messing up my weekly efficiency graph?
