images on image gallery at frontend not visible

Hello,
I have elementor pro, woocommerce, acf pro and acf frontend for elementor pro. So since a few days my image gallery doesn’t work on the right way. If I want to edit my products gallery on ace frontend form, I couldn’t see the uploaded images. But there are on the woocommerce product page (dashboard) and on frontend at the product as gallery in the right way linked and visible. What is wrong? I created this on acf field group as image gallery and set this as product gallery. If I deactived this, it is visible on acf frontend form, but not as image gallery on the product (frontend). Was there any update? Is it a bug or my fault? Thank you for your help, best regards Steph
