Not slowing down in KSRSS 2.5X

[tinyspy44]

KSP: 1.12.3 Windows 10 Home 64

Problem: Whenever I'm doing a suborbital flight or re-entry in which my orbital path touches the surface before entering the atmosphere from an orbital flight on KSRSS 2.5X scale I can never slow down quick enough to deploy chute and land. Is there a mod or any patch or simple fix I can get to make me slow down quicker. By the way for orbital flight if you're wondering why I can't just do a shallow re-entry I'm using retro rocket cuz it is Gemini and Mercury and similar.

Reproduce: Build a suborbital rocket with something like a Mercury or Mk1 Capsule and re-enter from a suborbital trajectory on KSRSS 2.5X

I don't have any mods that should affect this as I've used all my mods except Less Real Than Realism in the stock system and they haven't prevented me slowing down so I am confusion
