[CA] [CA11] red dots possibly depth how to change?

[mystery]

I am trying to figure out what these red dots are on my charts. I am guessing related to depth. I tried changing my minimum draft to 1' and they still show in areas where there is 5-6 feet of water per the chart.

I read the manual and it said during the initial setup that maximum vessel draft, safety margin, and minimum safe depth are set but these can be changed from the settings after initial setup. I cannot find these three categories.

In the attachment I circled the depths...

Any thoughts?

Thanks!
