Navionics charting questions - need help with charting?

I don’t think there is any way you can identify the bad ones. Why do you want to erase those?

I was "recording" at a high speed and the transducer sent a false 1000ft depth when in fact the true depth was 300ft. Sonarchart Live then created a large hole on the map, with a bunch of false contour lines. I have four such areas already on my map. It takes a very long time of boating on top of the faulty area in order to correct it completely, if it ever does at all... If I could somehow locate the coordinates of the fault in the .lsd files then I would delete them or change them manually and the problem would be fixed. Ideally that would be done with a Sonarchart Live editor app, if such an app existed... I am guessing that each .lsd file contains coordinate and depth information for a "block" on the map, but I don't know how to see that information...

Hoping someone can explain what's happening here... HDS Live with Navionics Platinum card, expired subscription about 4 years ago. I visited a lake (in NH) that I haven't een to in a couple of years, and many of the navigation markers are not showing but used to be there. Any idea what's happening, and how to I get all markers to show?
Thanks
