The port selection is just the communications path. The fact it is falsely identifying your board is probably because of (1) your development machine's drivers is miss-identifying it or (2) you have a clone UNO and the Chinese company put that in its firmware. Neither is really important.
The settings you make in the IDE are used to determine how your source code is compiled. Select the "Arduino UNO" designator in the menu Tools/Board: and you should be good to go.
If it doesn't work, cut/paste your errors here, and we'll go from there.
