What does this screenshot mean? Why doesn't nextcloud android app want to upload the `+389 KB` folder?

**Describe the solution you'd like**
Remove the folder and write `Empty`

If the app has uploaded all files (images, documents and everything else), why still show a folder saying `+389 KB`? Whatever shown should be relatively self explanatory with regards to the page, in this case `Auto upload`. My most direct interpretation is there are `+389 KB` worth of data in a folder that was not uploaded.... and the question is why? bug?
