One specific path on an smb share will only show 70 out of 145 items

I have a very weird issue with SMB video sources. While browsing it in the files section, it will only show the first 70 items that do not start with symbol [, ( etc.

I have tried renaming the files/.kodi and files/.smb folder rebooted the nvidia shield and tried again, but it’s the same.

Tried in ES File Manager, and it works just fine (you can even play them using Kodi from ES file manager), so access is not the issue. The share is configured on a Windows Server 2012R2 server, caching disabled, same as access based enumeration. All other devices (windows pcs, iOS devices have no trouble).

I renamed one of the shown folders by adding [test] in front of the name (from a different device) and it disappeared and a new entry was shoved in at the bottom, keeping the total on 70.

Kodi version: 17.1
Android: 7.0
Shield TV software: 5.1

I have looked through the logs generated by kodi, but I’m none the wiser.

Although this directory most definitely exists. And it’s always the “last” couple of entries shown in the Source browser.
