That makes it more difficult, the best I can tell you is to look at the html and all the classes and id values in it to make sure that everything that’s needed is there. The only thing that I can think of is that you’re missing a class or something that ACF is looking for. I’ve also looked through the ACf code trying to figure out what it is looking for and why it wouldn’t be replacing it in your field and I can’t figure it out. Some of the JS is just over my head.
