Disclaimer: I am tech-savvy EE. IIRC, this is how I fixed that small issue on mine - by swapping slots, and starting with the storage card in left slot first, then put map card in the right slot second; you try at your own risk.
First, power Helix off, then take both cards out (don't mix them up). Use your PC to move/copy all the HB files and directories from the map card to the storage card, and erase them from the map card. DON"T ERASE THE MAP directories/files. Mine is a Navionics card, so it is obvious which ones are which.
Now put JUST the data storage or HB card in the LEFT slot. Power up the unit and make sure you can look at your screen shots, or take one. Power back OFF after this is done.
Now put the map card in the right slot. Power back up, and you should be able to switch charts to that map card.
That's how I did it on on my Helix 9 MSI+ G3 with Navionics+ card. Maybe this will work for you. It seems the Helix checks the left slot first. Start with the storage card first in the left slot, the Helix will use it first. I then installed my Navionics card in the right slot. Now, all the HB stuff is on the left card (32GB), and nothing gets written to the map card (16GB card from Navionics). HTH
As for the settings and glitches, mine are solid, so this isn't normal. I always do a "reset defaults" after an upgrade, or if things get wonky. You probably know this, but to see ALL the options and menus on the Helix 9, you have to go into the system settings and change mode from "Angler" to "Custom". HTH
