Yeah, its normal and good to have 2 different channels, stereo is always better then mono. Ok, when left channel has a annoying noise, it will mabye better to delete it and convert the right stereo channel in mono but, Stereo > Mono because it has spatial audio informations. In my example screenshot i found just a mono file on my pc. When you create the loops, create a new Stereo track instead of a mono track, fading and cutting work in the same way for stereo sounds.
