Again with the Gleaner k

'm trying to cut soybeans in the next couple of days here and I'm cracking about 20% of them if not a little more. I am running the concaves wide open and the cylinder speed as slow as it'll go. I'm having no problems with them threshing but I'm having an issue somewhere with them getting broke. I tried running at the recommended speed and clearance and broke probably half of them I'm trying to figure out what to do here as I've never run a combine before. Maybe taking concaves out will help where would those be located?
