Having trouble activating multiple TestExecute floating licenses

In addition to our TestComplete floating license (with 3 seats) we also have an instance of a floating license for Test Execute on our license manager with 1 seat. We are trying to replace the latter with a recently purchased TestExecute floating license with 2 seats but getting an error message "Another license for the product is already activated on the computer" We have the new key but how do we get it activated? I've attached screen shots of both the error and the existing setup on our license manager. Thanks!
