I found the issue and now I understand what they meant.

– Fixed an issue where Heading was not correctly displaying in the Heading Databox or Overlay.
– Fixed an issue with SmartStrike Search involving search criteria checkboxes.
– Fixed an issue with Lakemaster Shallow Water and Depth Highlight (Note that this created a follow-up issue that will be fixed in the next release.)
– Fixed an issue where Louisiana Delta Cards (LA Delta) could not be read.

Thanks for the quick response! I’ve been running Helix for years but just upgraded to the Helix 10 and noticed it for the first time. I thought I may have found a hidden map setting or turned something on and couldn’t find it again. Not the end of the world, but I definitely don’t like it when I’m ripping across a newish lake and I have all these shallow areas that are actually deep holes haha.

I’m thinking about going back to the version before the new release, has anyone else tried that?
