Issue presented first after last patch

Playing Exsang Miner. Detonate Mines appear as 2 skills in the selection menu. Detonate Mines (since the latest patch) continually maps to the O button as if its a default. If I try to map a different skill to O, it doesn’t stay - every time I pass through a portal, it defaults to Detonate Mines and the skill I’m trying to use (shield charge) is not mapped to any button. I tried to map detonate mines to other buttons, but it remaps to O (always) when passing through a portal and sometimes randomly in maps. I tried to map another skill to O and it was replaced by detonate mines as well. I can’t fix it with anything I try. This was working just fine before the latest patch. further, when I go into the skills menu, to put back shield charge, its highlighted - its icon is sort of standing out of the menu. Truly weird. I am detonating mines through the atlas (on movement); I don’t use manual detonate mines at all. I’m surprised no one else has reported this; I even changed controllers last night to see if the problem was hardware (it isn’t). Thanks.
