wrong synth on segment

Hello,

I have two tracks with drum segments on each that I assign 
to the Hydrogen drum synth. Problem is that the sound output 
is not Hydrogen but Grand Piano form the GM synth, just 
yesterday this changed to BOTH the grand AND the drum kit
sounds seemingly depending on the staff note.

{Suse-Tumbleweed & Rosegarden-22.12.1-2.1}

Is there a rosegarden 'upload' facility where I could 
upload the *.rg file consisting of just these 2 tracks?

I've had issues before with notes not ending/closing,
is there a way to start a new track but paste the entire 
staff and NOTHING but the staff notes to it?

TIA
