Buggy Pattern Editor??

Tried following:
I have a SD1 style and I just want to do simple thing - I want to copy the content of e.g Chord5 to Chord4 as I want to have also live guitars in this style. What have I tried so far:

I made a copy of this style and have both of them in the User style section. I select one style as the source style and one as the target style. Then I tried to copy the track. Some of the tracks can be copied, others ends with a generic copy error. Is there anybody who can help, or is this another bug?

Meanwhile tried some other topics on the style editor - sorry KETRON, but the style editor is NOT really usable. If I try similar things with my old XD3 everything works fine.
