Why are acoustic kits so low volume in GA5?

In groove agent 5, the hip hop and electronic drum kits are fine, but the acoustic kits (such as the ones from The Kit) are super soft and you have to crank the instrument gain up to 12db to hear them and get a proper signal. I was gonna buy GA5 but if there isn’t a fix for this it’s a deal breaker. Hard to believe this got out of steinberg quality assurance testing like this. Anyone ?
