Hi @freakymiky
Just to clarify, the issue is that you can’t svae any more than 16 sub fields when editing an ACF field group.
This is most likely due to a server limitation. You can only posts so many variables in one go, and this is why you are not able to save all the data on the page.
What you will need to do is split the fields into 2 field groups. This way you can save half the data
Thanks
