Hi @dennisterrey
Could you please share the JSON or XML export file of your field group so I can test it out on my installation?
Please keep in mind that you’re not supposed to change the field name as it can cause issues in the future. I suggest you change the field label instead.
Also, could you please make sure that your max_vars setting is not the one that caused this issue? This page should give you more idea about it: https://www.advancedcustomfields.com/resources/limit-number-fields/.
Thanks 🙂
