Bug description

whilst syncing a folder structure with many smaller files the status display looks awkward:

initially the display makes sense, e.g. saying "140MB von 248MB" in my case using German UI but after a while it changes to what's in the screenshot attached.
when the screen is refreshed, e.g. by clicking on settings screen and back the count is back to normal
Please note:

• the structure was moved in one go into the sync'd folder on the Win PC. sync client picked up the change and started syncing as expected.
• folder structure/files might change during the sync, which usually doesn't cause issues, changes are picked up straight after the sync is done, causing a new sync.

Steps to reproduce

• set up an empty sync folder
• let it sync
• move a directory structure in with many sub-directories and small files (in my example that almost 9k files structured in 1027 (sub-)directories

Expected behavior

counts displayed should be accurate

@dt64 could you share your configuration file and also some info on the file size ?
I am suspecting the bulk upload feature or chunk upload to be the issue
So I would need if you were uploading small files or very big ones

[dt64]

the dir structure includes about 31k files in 3,5k subdirectories using 1,22GB. Average file size is pretty small.
my config file is attached. There are two accounts configured. The issue was with acc ID 1.

With the upcoming release of the desktop client (version 3.16.3), the bulk upload feature will be temporarily disabled.

We understand that some of you may rely on this feature, and this decision wasn't made lightly. However, we've encountered ongoing technical issues involving the interaction between the client, server, and underlying systems—including network stack and Qt dependencies—that impact the stability of the feature.

In prioritizing a smoother and more reliable experience for all users, we believe it's best to disable bulk upload for now. The overall benefit of the feature does not currently outweigh the potential for disruption.

If you're unable to update to version 3.16.3 right away, we recommend manually disabling the feature on the server side to avoid any issues:

We appreciate your understanding and are continuing to work on improving the experience.
