No That's a very very minor change in sound. One thing I understood, the bass is the issue,it's too wideI think if you look at the OH and room Width, you will see that the knobs are full right. In the close mics, you have you panning. I wonder in your software if the panning on the close mics are fighting the Kit mics? Just looking at the close mic panning, everything looks pretty good, nothing hard L/R. Just for fun, try bring your room and OH width closer to the middle and see if that doesn't sort it out.
