AEM 6.4 | Restore Tree option deleting all content from AUTHOR and PUBLISHER

Hi all,

Hope everyone doing fine. 

Has anyone experienced this DELETION issue related to "Restore Tree" feature.

We are on AEM 6.4 . We were using "Restore Tree" (Tools > Restore > Restore Tree) option from "Classic UI" since "Touch UI" still does not have this feature yet. 

https://docs.adobe.com/content/help/en/experience-manager-64/classic-ui/siteandpage/classic-page-author-work-with-versions.html#restoring-a-tree-from-the-console

1) What we noticed was when we used "Restore Tree" option and selected a hierarchy which we wanted to restore - This process deleted all our other content pages (everything it deleted except the one which we selected for restore).

2) Then we saw that even everything was deleted from Publisher Instance too. To troubleshoot this further we looked at replication log and clearly we could see DELETE replication messages there in replication log. See sample replication log below

Has anyone else faced same problem of DELETION while using "Restore Tree" - Is this default behavior of AEM. Seems like a bug.
