Parts of the subtitling is repeating

Strange issue.

Parts of the subtitles repeat after a few seconds. otherwise they run synchronously, but there is always a bit
of (same text) subtitles from the past inbetween. Anybody had this befor? Can’t find a similar issue on the www.

I run Jellyfin in a Docker container in Open Media Vaulth 5. For the rest everthin works smooth :wink:
