Resource/Method Window creation when Copying Test Step From Functional Suite into Load Test

I've created a test suite in one functional test suite and copied in other test steps from different functional suites.  A 'Resource/Method" window has populated on each of these imported test steps, but it will not allow me to edit the resource endpoint which of course if different for each imported test step.

Any ideas on who to remove this window so I can edit from the Endpoint window?

I tried adding my '/create' method to the endpoint in hopes that it would over-write the method, which it did NOT.

No apparent way to remove the "Resource/Method" window either.
