Logged 1400 hours and 不思議 is breaking my spreadsheet

I'm currently at Hour 1,402 of my Phase 2 comprehension routine. I mapped 不思議 strictly to 'mystery/wonder' in my database based on Core 2k parameters. But during today's 45-minute active immersion block, I heard it used as 'strange' or 'odd' like three times. This completely breaks my 1:1 translation node mapping. Does this require a separate card or is my database wrong?
