Required fields inside a group inside a group aren’t validated

Hi there, I have a form that is using your pro plugin. It uses the multistep and conditional features. On Step 2 of the form I’ve copy pasted below, you will find a dropdown. Once you select an option, the last option of each group opens a new group for a textarea field which is meant to be required, but if I leave it empty it does not validate. Can you please review?

Here’s a screenshot of the field (last one): https://loom.com/i/889db3fb585146ee84204ad19be6eafb
