HDT BBP COSIO HD Physics Oddity?

So, I wasn't quite sure where to ask the question, nor if anyone really knows what's going on because after hours of searching, nobody had asked this question or had this "problem" (?)  Essentially I've noticed that when I build my body in bodyslide, the breasts are perky and full.  When I go in game however, and physics are applied, this isn't the case as the breasts "shrink" ever so slightly.  Only it's not really a shrink, it just looks like HDT physics pushing them down on themselves so they're not as perky, and look smaller and less full.  The curious thing is that when I press ~ (To go into console commands) or go into any paused menu where I can still see my character, my breasts revert to their normal fullness and perkiness.  My assumption is that this is caused because the physics engine doesn't function when game time is paused, and that they're simply not being affected anymore, though I could be wrong.  My question then, is this:  Is there any way to still have fully working breast physics without having said physics "push down" my breasts when idling, make them look like the body I've built instead of a slightly squished version?

In case anyone else comes across this problem in the future and stumbles across this thread, I figured it out.  I had BBP installed when it was unnecessary and it was being overwritten by COSIO anyways, however when installing XPMSE I selected the BBP physics animation rig, thinking that I needed it because I had BBP installed.  The fix was to uninstall BBP, reinstall my skeleton animation rig as HDT instead of BBP.
