How to avoid navigation signposts when I edit a track

I love LM Pro and have used it for years, just maybe not as intended. I never use navigation tools but prefer just an accurate track on the map. I can see when to turn left, I don’t need a panel to tell me! But now I’m planning a long 5-day hike and I have created each day’s tracks using the helpful auto feature that (mostly) follows hiking trails. Of course I then needed to make some track corrections to straighten out some deviations or to add some. I used the track edit tools successfully to correct the track, but after I’d finished I saw the track was littered with unwanted “signposts” that took me a lifetime to remove (each one required about 10 button presses to delete). I have tried to use the guide to avoid bothering you, but can’t see how to set a preference to NOT add these signposts, or to remove all in one step.

Your help would be hugely appreciated. Thank you
