Songs played through Rekordbox get louder during breakdowns

I have the most current version of rekordbox connected to CDJ-3000s and a NSX2 mixer.  All have the latest versions of software/firmware as of June 1, 2023.  When playing a song, the volume gets noticeably louder during breakdowns/vocal/instrumental sections.  It's very obvious.  In fact the levels will go into the red slightly on the mixer sometimes.  This has been a problem with Rekordbox for quite some time even on previous versions.  I have auto gain turned on in the settings.  The same track played from a USB stick will not get louder like this so i know Rekordbox is the problem.  Often, it gets so much louder that i have to turn down the gain or headphones as it's noticeably louder.  How can i fix this?  This one problem alone has me considering switching to Serato.
