Help with SMP configs

[JannickPvP2151]

Hey everyone.
I am running the Athena Collection from NexusMods with a custom made TNG Futa Addon (a conversion of slash197's TBD SE - Futanari Balls Lover) and my physics are breaking with the cock and balls. I wanted the cock to rest on the balls and everything "realistic" (what should collide in reality collides in game) but everything is breaking. Can someone help? I am running FSMP 2.5.0.
In the attachments is an image of what I mean, my TNG Addon and my configs.

Start by increasing the Y-axis linearUpperLimit and the X-axis angular limits. May also need to decrease Z-axis linearLowerLimit.
