Well there are two ways that I’m aware of, but the one that acts finicky, on my system at least, is having only that track selected, park the timeline indicator over the edit & go into trim mode (it defaults to double roller), & hit delete. Sometimes this works & other times it thinks I want to delete the whole track, but I never tried to figure out what or if I was doing something wrong.
Or you can do the same as above, but instead of hitting delete, while trim mode is active & double roller, you can press ctrl as you drag either right or left & it will snap to the beginning or end of the clip, therefore removing the add edit.
Try both
