Slide Not Save,

Hi,

Please open the browser console, replicate the issue, and share any Javascript errors there with me.

This article will guide you on how to open the browser console: https://support.airtable.com/hc/en-us/articles/232313848-How-to-open-the-developer-console.

Also, please check if the issue happens when only MetaSlider and the Twenty Twenty One theme are active.
