i am trying to remake my kicad schematics in flux. i went to import my kicad symbols and i get

Astro-DB-altium-import.kicad_sym

Imported from KiCad Part

Cannot import KiCad part file because it isn’t the correct format.

Learn more. Need more help? Report an issue.

also I tried to attach my kicad_sym file and it refused to let me attach it. I also tried zipping it and it refused to attach that file.

I am using kicad 9. do I need to revert the symbols to the older version?
