This is a feature, not a bug. Overload grants you a 3rd skill bar. It programs this bar when you first slot and activate the mode. You can change the skills on this 3rd bar manually, and it will remember what your selections were afterwards.

This happened to me in a vet group dungeon last night. I've had the same skills slotted on my Overload bar for awhile, but for some reason it just reset and left me without my magicka sustain dark conversion and my execute for the one boss that I noticed. I changed it back right after.
