MediaBrowser - All thumbprint the same

Hello,
I've tried everthing and I cannot get MediaBrowser to show the correct thumbprint for my movies.
My server configuration Serviio v1.3.1, WIndows 7, All files in the same directory, XBMC generated NFO and JPEG. A hint may be, 1 movie in an embedded directory shows the correct thumbprint(jpeg).

Please help,
Ken

There migh be a (hidden) jpg file in the folder that is used instead of the required ones. Check for it.

Thanks for the advice. Unfortunately, there are no hidden files. I have noticed, Serviio use the alphabetically last .jpg file in the folder. If there is only 1 jpg, that file is used for every film.

My experience is that once a thumb is cached for a particular key, it cannot be updated. You must remove the thumbnail files from the library and let them rebuild.

That might be the case for online stuff, not local.

Can you post detailed log of browsing to the folder in MB?
