Page disappearing

I copied today a block from my daily journal into a new seperate page.
Within the original journal did I leave/created a reference to the main block of the page (first bullet).
After a short while did the block id change color and was the new page gone. It disappeared.
The same thing happened later today.
I’m sure the page creation was succesfull since I double checked by opening it within Logseq and manual closing it after checking.

I’m using Logseq on a Windows11 computer and have the latest version installed.

Looking into the directory with the Windows Explorer reveals that the missing page is indeed gone. However within Onedrive could I retrieve the information by restoring a previous version of the journal.
