I hope it works but you will have to test that out, the other poster seemed convinced that would this way and it should. Hope it restores your faith in using ACF, personally I’ve used the other field manager you mentioned and it certainly doesn’t have the nice interface that ACF offers. But I’m a big fan of ACF and base a lot of plugins around it so I’m heavily biased in favor of it.
Keep me posted if you don’t getting it working this way I’ll probably fire up a test site right now I don’t have something active with WPML I can try it on.
