Page content lost when importing from dev to test environment


we were trying to move the XAR file from dev to test environment with export and import feature of XWiki. While importing, everything else seemed to be working fine, other than that the specific page and its content. This page has been moved with Confluence Migrator Pro and had some photos/content in it. When moving from dev to test, this page became empty in test environment after importing the XAR file, but in the attachments section of this specific page, we can actually see the content uploaded in attachments, but not in the page itself. I was wondering what could be the reason behind such issue? Thank you so much.

How the page looks like in dev:

and how the page looks like after importing to test:
