[Koha] Koha 3.18 adding T-Prefix to all scanned barcodes

We have a library system which we migrated from Follett years ago. We left all of the old barcodes with the T-prefix, and use the barcode input filter which removes the T-prefix from our old barcode stickers. Lately, a different issue is occurring with checkout. Most of our barcode stickers have no T-prefix, but when scanned into the Checkout field a T-prefix appears. I'm not sure how Koha is adding the prefix. Is there a setting I'm missing? Thanks!
