Form bug when repeater field is added to it

hi

I created a multi-step form and used a repeating field in one of the steps.
When testing as a user, when I complete the form and get to the repeating field step, if I don’t add a new item to the repeating field, everything is fine and the next step is active, but when I add an item to the repeating field The next button no longer works, and when I checked the codes, a disable property was added to the button and it was no longer clicked, and when I deleted the repeated field item, the next button was activated again and went to the next step.
This problem occurred in the latest version, 3.0.8.
I even disabled all plugins and only Jetform and Hello template were active, but the problem still persists
Please check and guide me
