How do I make my capsule fit the character mesh?

I’ve been attempting to make the capsule fit the mesh, but it doesn’t work the way I want it to when I add a box collision. My mesh collides with the other mesh, causing the AI to glitch and get pushed. I also tried setting the AI to block anything, but it didn’t work. Is there a easy solution to my problem?

hello
at first attachment , you can select capsule and then use Scale ,Move or Rotate to fit capsule with mesh
is that small icons exactly under “Hide Unrelated” Button

Thank you but that doesn’t seem to work it either instead it changes the size of the mesh? Its a character blueprint.

I had the same problem, this video solved the collision and it worked, but I don’t know if there is a better way
