[DVD-o-matic] Lost in transcoding

Yesterday I tried to make my first DCP with subtitles that were not burnt into the source file. It didn´t work out that well, the swedish translation was lost in the process. Yes, the checkbox "with subtitles" was filled. Am I doing something wrong or is DVD-o-matic unable to extract subtitles from this source file? The source file (.mkv) origins from the sub-DCI distribution system used for documentarys and art house movies in Sweden until now. Source file tested on a Tvix Slim S1 running 2.1.0, subtitles visible on screen. DCP file tested on Dolby DSS220/IMB Cat745/Barco DP2K-10s, no subtitles on screen. DSS220 running 4.5.4 (2). DVD-o-matic ver. 0.80 (as I remember) Magnus Eriksson Zita, Stockholm Attached: Mediainfo from the source file.
