Unwanted sound effects when moving position within a track

Cross DJ 2.3.0. External ASIO soundcard. No controller, just using mouse and keyboard
I will often be playing a track from e.g. player B, whilst in player A I am previewing a track to choose where to set some locators and/or finding an ideal exact position where to start playing a track.
There are two places where I can visually see the waveform of the track. I have marked these as 1 and 2 in the attached screenshot.
To position it accurately I will be using the top one - marked 1 in the screenshot (for myself when actually playing I have it in scrolling mode)
I do this with a mouse click+dragging in the waveform.
When I do this I get unwanted sound effects - either like a needle scratching or the squealing like holding down fast-forward on an tape player.
Can I do anything to do what I want to do, but not get those sound effects?
