wordpress/tmp folder filled up with woff files

Hi there, I noticed a lot of tmp files being created in the wordpress/tmp folder. About 80 gigs over 2 days. When I copied a few of the files over to investigate I could tell they were woff files. Most of the tmp files looked like this “pxiByp8kv8JHgFVrLGT9Z1JlE92JQEl8qw-######.tmp” or “4UaZrEtFpBI4f1ZSIK9d4LjJ4mE3OwtmPXws9Iq2uBiM-######.tmp”

I turned off all caching plugins but nothing worked until I disabled Kirki. Not really sure whats going on here but once I enable it again it starts filling the tmp foler again with temp woff files. For now I’ve disabled Kirki and things are back to normal.

Any help would be greatly appreciated.
