Bug: End Marker not working

I have an action, that at the end marker the next song will play. Unfortunately the song plays endlessly and it doesn’t switch to the next song.

Did u click “Apply to all”?
(Using VL with “Next Song @ End Marker”)

Hi!
Cannot confirm this. I suppose you use latest version - 3.0.36.
I created new project, added 4 songs, for every song placed End Marker in differrent positions, then set Actions - Start Next Song, Song End Marker, Do this for all Songs.
And everything works as expected.

I have made a video about it, can i upload it ?

Yes, upload to Youtube and paste a link here.
Is there Song Action settings visible for the song that skips End Marker?
