Group channel problem

Dear all
There is a problem that I dont know how to solve. I have added group channel to selected channels ( 2 channels ) and every time after I had deleted/removed this group , those previous channels had no sound.
I have cubase elements so there isn’t any function like ungroup or unlinked. Is there any option to get rid of group and have original channels with sound.

Re-assign the outputs to the desired output bus. In your case probably the stereo out.

wow, works perfectly ! Thank you very much !
