I have tried setting nonegotate and hard coding speed with no results. Each time it either doesn’t accept the command or I do it through the web interface and it appears that nothing has happened. Can you send the cli sequence you would like me to try for changing auto negotiate and setting port speed?
Port capabilities with no SFP Transciever in the slot:

Port capabilities with a SFP Transciever in the slot:
Note that the SFP is correctly identified. Both speed and type.

Without an SFP Transciever in the slot:

With a SFP Transciever in the slot:
Please note that the port speed changes to 1000Mb/s. No fiber is plugged into the transceiver and the transceiver is correctly identified as 100Mb/s. Why is it doing this?????
