After edit content data lost

Hello,

In my site I have used Enfold theme which have Avia page builder to create pages

Issue is when editing the page, content blocks from the bottom are removed which was edited.

Sometime also it will removed after edited 2-3 times.

I have created test page for home. You can edit and checked the issue.
