Adding transition pulls in audio already previously cut

Using Premiere Pro 2017  in Windows 7 pro, and I'm a beginner user.

I'm going mad over adding a transition:  I've cut a clip using the razor in the timeline. It runs right into the next piece of the clip, just as intended, but theres a slight jump in the characters position as one clip runs into the next. 

I thought the obvious thing is to add a transition to smooth over the jumpiness of the cut.  Only when  I add the cross dissolve Premiere brings back in some audio I'd already cut, making the transition useless to me.

When I have no transition, the audio is perfect, but the visual has that obvious-and-expected jump as one moves to the next, but add the transition, and the visual is a smooth transition but this infuriating audio section 'comes back' for a fraction of a second... searched everywhere and can't find an answer - please save my sanity with a suggestion or some advice?  thanks  Chris
