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

### ⚠️ Before posting ⚠️

### Steps to reproduce

1. Open Nextcloud Android App
2. Open Folder (e.g. "Forms")
3. Select/Open PDF File (Containing Form Fields) in PDF Editor App (Xodo)
4. Modify the content of the Form Fields
5. Close the Document
6. Back in Nextcloud Android go "back" to the Folder "Forms" containing the PDF File
7. 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.
