Jeffrey, I’ve looked into your problem a little further.
The cause of your woes is the validation field plugin. This plugin uses non standard field keys.
If you show the field keys of all of your fields you will see the difference. all of the ACF fields keys start with field_ and all of the fields that you created using the validation field add on to not use this naming convention.
The data is being saved, but ACF does not know how to find that data because the field keys do not conform to what ACF is looking for.
You need to talk to the developer of that plugin.
