adobe indicates firefly generative ai used even I don't use ai tools

Im creating handmade paintings semiprofessionaly and trying sell them as nft. I upload them to marketplaces like rarible or opensea. There is a section for each paining at rarible named as credentials and it says its includes generated image by firefly ai. I sell nfts as no ai used human made art , I never use ai. How can I fix this ? Sory for my English, sorry if i posted in wrong forums and I lack technical information. Thanks for help.
