One keybinding key not working

Skill slot 2 in my keybinding is set to the letter “S” on my keyboard for character Cappycarnage. When I press “S” my character MOVES, as if it is still in the default WASD. If I click on the spell on the spell toolbar, the spell activates. For other Diablo 4 characters, the “S” keybinding works as it should. IMPORTANT: It is a problem with ONLY Cappycarnage. My keybinding setup is identical to the setup for my other characters. I’m not sure how to fix this. Please help.
