*Update** so I was adjusting my Gravitybox sense6 toolbox and trickster and ended up losing my double tap to home again.. But I did a few things right after that seemed to have fixed it but I'm not sure exactly which did it:
1. In sense6 toolbox> sense mods > unchecked Reduce gap
2. In Gravitybox > Navigation keys actions > Under Home Key > Double-tap action > chose Show recent apps
*note: this didn't work for me when I had chosen stock button layout in aroma installer
3. In trickster under Specific > Screen Wake Control > turned off Sweep2wake, turned off Logo2wake (this might've been already off, not sure), and turned off Logo2Menu. I left Pocket detection and Logo2Menu on
Everything seems to be working fine now
I feel like what I did in #2 did the trick seeing as when I initially installed with stock buttons all the adjustments I tried to make didn't work.. But this time since choosing Logo2Menu in aroma I was able to fix it..
