I can't get phys material from landscape in 4.24 using a trace by channel

After updating to 4.24 my foot step sound trace on my landscape can’t seem to find the phys material. Its all still working fine on static mesh but no luck with the landscape. Built a new project also and still had the same issue.

I was on .21 before converting so not sure if I missed a good deal of changes but having trouble figuring this out.

Thanks for any help!
