Hi Jaace,
First of all, do you have acf_form_head in your page, as well as acf_form?
I built a site around 2 months ago that has a mass of front-end fields, text, radios, selects, gallerys, repeaters, etc. All of these worked fine. I do however remember having a lot of trouble whilst messing around with the Gallery field, it took a while to get working.
If you need some more help give me a shout, i’ll let you look at the dev site and the code used to create the forms. roartex at me dot com
