So I'm giving your tunes a listen and it's odd that some of them have heavy compression and others don't. You mentioned this being quiet, is there a limiter or some similar unit on the master out? Perhaps there's a compressor on a specific mixer? Not sure how your workflow looks but you had bass drums breaking out of the compression at 1:04, 1:48, and 2:10. It's visible in the waveform image above. Someone mentioned FL does that compression by default, something has to be turned off or bypassed manually. I use Reason and only recently figured out to check the fidelity units on the master out. Literally one button was the difference between bad compression and more mix room. Was eye opening.
Seriously, track sounds like it's pretty hot but it would be even tighter if you could find what's shaving down your fidelity :)
