Song Editor and Beat/Bassline Editor don't play together

Having trouble with LMMS? Ask about it here.
hello gentlemen,
first I prepared Bassline0, it played OK both in B/BEditor and Song Editor but after I added a sample to Song Editor (drums_loop.ogg) it stopped to play the Bassline and plays only the sample.
So B/BEditor plays the Bassline Song Editor plays the sample. What to do to combine their playing?

do you have any 'muted' tracks in your project?
If not please upload the project and send me an im with the link, i will look on it
thank you, musicbear

once again I have to apologize, there are no 'muted' tracks in the project I just had to learn better that Beat/Bassline does not sound in Song Editor until the first rectangular in the track is clicked and changed its color. Hopefully, I won't repeat this folly question any more (which does not exclude equally silly ones).
