Going to active mode changes the impedance of the bass as the amp sees it. One big difference to us is that we get to run longer cables, usually without an increase in noise. OTOH, if the cable is heading south it's going to act kinda like a noise antenna which may be more apparent when the preamp is out of circuit. Bring the preamp in kind of suppresses the noise because of the impedance change.
So, all other things being OK, have you tried a different cable? How does the jack feel?

Another thing, how much different the boost mode comparing to regular active? I may be imagining but on my bass the difference is not that big. A bit more clarity, but that seems to be it.

The difference between passive & active is perceived as more of a very slight voice change than a gain increase; a little more aggressive sounding. Switching to active with treble boost is a hellacious brightness switch.
