We are facing issues with multi image sequence and video additions for our new projects

Hi everyone,
We are planning to launch our website this week but need to fix the Gallery and Content ASAP for all our projects. We’re unable to upload more than six images/videos in a project (under CMS) even though we have tried adding MULTI IMAGE SEQUENCE and more than 6 images in a project. After publishing they are not showing up.

Sharing some screenshots here.

We tried connecting with the original template provider team. But they haven’t replied yet to any of our emails. The site is built on CIRCLE WEBFLOW template.

I’m sharing the Loom Video links that highlight our problem. Hope they help.

I also tried adding a new project and using the same feature, but it’s not working.

Any help in fixing these would be great.
