Audacity adds a random unwanted effect

When I record audio in audacity, it comes out normal, but if I highlight any part of my audio, it automatically adds reverb and I cant undo the reverb without just deleting the recording. How do I get rid of this?

Windows playback enhancements can automatically add reverb,
here’s how to turn them off …

[ There could even be another layer of audio enhancements ]

Thanks for the help :smiley:
