Modifying WAV files.

Hello BB tech support. I’ve imported some WAVs from BB (kick, snare, toms) into Cubase and have made very small tweaks to the EQ on whichever instrument. Saved the new WAV files and imported back into BB. But I’ve found on some of the new WAVs, the sound is too powerful/distorted/extra-reverbed. But I’ve been diligent to make sure the new WAVs output level is not increased, etc. when I save it from Cubase. Does BB add some effects to the base WAV samples? Or what is it that I’m doing wrong? Thanks.
