filter broke my data

filter broke my data

I uploaded a file recently from Sheets and it has top 2 rows frozen, with table headers in second row and each one is filterable. somehow my first 2 columns became unfiltered and no matter what I do I cannot reapply the filter?? also didn't realize they weren't adjusting when I was sorting the rest of the columns and so now that data is completely off with no way to fix it except to re-upload my original sheet.
