Highlight color spills to next word

Hi.. the highlight colour spills to next word. how to remove a highlight collar. I cudnt see any options.

Context- As I add the words & select highlight colour, the colour keeps spilling to the next word also. There is no problem if highlight after I complete finished the sentence & then add highlight colour. but that’s kinda irritating. I was told to remove the span <> but it’s kinda confusing where the span brackets open and close. Is there anyway to remove highlight colour. I cudnt seee any. Kindly help!!!
