Issue with drag and drop patterns with low complexity

I have just got ga4 and I was putting together a drum track, I picked a pattern but wanted just a low complexity on it, the problem is when I put it in the project it plays some weird pattern nothing like what I had chosen, and it seems one of the fills is being triggered. When I raise the complexity above 10 then it transfers fine, anything below 10 the problem appears.

Could anyone tell me if it is something I am dining wrong?
