I recently upgraded my GPU and the Radeon software shows that it recognizes the PCIE 4.0 card but is running it at PCIE 3.0 bandwidth? I can not figure out why this is happening, or am I reading the Radeon system properties incorrectly?

I tried to reinstall the software/ drivers, i even did a factory reset install of the radeon software, this did not change anything.
I'm not sure what to do now?
