All Characters jitter after I create a custom trace channel

I created a default third person template

Created custom trace channel set to block

Created new character class and added a USphere and UCapsule component (and movement functionality)

Created A derived blueprint class of the new character

In the blueprint class I set the sphere and capsule collisions to ignore everything and only block my custom trace channel

The characters started jittering after the first test

So I resorted back to the untouched default third person character and it had the same jittering affect as the new character class

I replicated this in 4.24 and it works fine it only started when I started new 4.25 project

I dont understand why the default third person is jittering when i didn’t touch it
