Edit Reason: Added a potential solution

Love the Ropes! makes great wire/cables
So I have a rope that is in a single loop (not touching) similar to a wrapping an extension cord, and at the apex (top where the 2 ends are close together) I made another rope around the apex, and I closed the loop ends to form a zip tie, again, this zip tie doesn't touch the cord (even checked the rendering from 0.8 to 1 to verify). but when I hit play, the cord bounces out of the zip tie loop, and the zip tie falls to the floor.
***EDIT and how I think I solved it... but is it correct?***
Zip tie blueprint-
thickness 0.03
Resolution 0.3 (the lowest I could make it... 0.25 "did" work, but if I moved anything it broke the zip tie)
pool particles 2
Zip Tie Distance constraint: stretching scale 0.2 (had to oversize the zip around the cord, then on runtime it shrinks)
Zip Tie Bending Constraints all zeroes (zip ties shouldn't bend)
Zip tie was anchored to a cube in the middle by the loop apex
Cord Blueprint:
thickness 0.1
Resolution 0.6 (the lowest I could make it... lower and it would fall through the zip tie)
pool particles 100 (default)
Cord Bending constraints all zeroes (emulating an electric cable that's stiff)
anchored the ends of the loop to cubes
Further Edit: if I unanchored the zip tie, the loop sides popped out of the zip tie, so I increased the stretching scale to 0.4 (Corrected), added High static friction and it "mostly" held in place, gravity pulled the loops ends mostly through the zip tie, but it still held a "small" loop
Enabled Surface collisions to reduce resolution and it really helped. now the cord acts like a heavy gauge power line.
Enabled Self collisions so the cord that looped, doesn't overlap itself, and instead rests besides itself.
