Unable to rename test

I am on TC 11.11.1064.7

A created a new test to replace an existing test. 

I removed the existing test from the tree in the project explorer.

I opened the "Organize Tests" window and removed the existing test from there.

I moved the new test to the proper place on the tree.

I attempt to rename the new test to the same name as the old test. I get "A file with the name "x" already exists on disk at this location.

Where am I not deleting the original test? I need to get past this error.

Thanks.
