PS detects duplicate GPU

[DCK]

A couple of weeks ago I had to roll back the driver on my GPU so that it would work in PS. Ever since that time, I show a duplicate of the GPU in my OpenCL window. It may not be causing any problems, but it can't be helping.

Is there a way to remove the duplicate? Should I bother?

Should I tick off one or both GPUs in the OpenCL screen?

Thanks.
