Changes to Files Being Discarded When Using "Sync" on Folder

Steps to reproduce

Open Nextcloud Android App
Open Folder (e.g. "Forms")
Select/Open PDF File (Containing Form Fields) in PDF Editor App (Xodo)
Modify the content of the Form Fields
Close the Document
Back in Nextcloud Android go "back" to the Folder "Forms" containing the PDF File
Click on the Kebab Menu Symbol next to the Folder to open the Bottom Sheet Menu and select "Sync"

Expected behaviour

The "Sync" feature Syncs all Files contained in the Folder and its Subfolders making the changes visible on the Server

Actual behaviour

After the Sync is finished the Modified content is gone and the "last modified Date" is also not changed.

But this only happens when using the "Sync" feature for a Folder.

if i do the exact same steps as described above and then click on the Kebab Menu Symbol next to the File to open the Bottom Sheet Menu and select "Sync" then the changes are visible on the Server as expected. Also if i modify the File as described above and then open the same file again (triggering the Sync) the changes are visible on the Server.
