On the right-hand side of K2-D2 title bar, there's a push button labeled "S". Push it and it will enable automatic staging.

Loading the ActiveTextureManagement plugin solved that issue for me.

I found through experiments that setting the aero-capture periapsis at 16,750 km is ideal height for my space craft configuration. I point the craft retro-grade while during aerocapture manuvers (YMMV). I do radial burns for rough adjustments of the periapsis (fuel efficient), and pro-grade/retro-grade burns to fine turn the periapsis (0.1 dv or less).
