Single audio track in Media Player, double in Premiere?

Yesterday I recorded a video using Logi Capture and a Zoom H2 mic. In Media Player, it sounds fine. But when I imported it into Premiere, the sound track is duplicated. That is, Audio 1 shows two identical sound tracks, there is no Audio 2 track. Is there a way to make Audio 1 a single audio line, as it was recorded ? 

[I have a PC and am running Premiere Elements 2020, version 18.0.]
