Survey Form Star - Not being displayed anymore [RESOLVED]

Hi there,

I’ve been using Gravity Forms Survey Add-On for 2 years now.
Suddenly, the stars don’t appear anymore, only number form 1-5 are being displayed.

Notes, surch as excellent, or bard are appearing white on white.
So people don’t know if they are putting excellent or bad…

How can I fix this?
What can cause this issue?
Thank you!

This issue was resolved by disabling the deprecated legacy markup feature in the Form Settings area of the form.
