Possible bad thunderbolt port on 2018 MacBook Pro 13"?

I have a weird issue in that my MacBook Pro will incorrectly detect my external monitor only on one of the 4 thunderbolt ports. I have an LG 27UD88 connected via USB-C cable. Every other port detects the display correctly as a 27" display. However, the one port detects as a 30". I tried resetting the SMC and nothing

Wrong:

Correct:

Anyone have any ideas on what I should do next?

Thanks

I solved my own issue. I followed old instructions to reset SMC. As it has T2 chip I needed to follow instructions here https://support.apple.com/en-ca/HT201295
