Double repair key?

[[AККИ CS:GO]vk.com/bdsmacc]

Maybe someone can help me. In game, Dungeon Defenders, I somehow managed to bind a second repair key where my first abiltiy should be. How can I fix this?

all keys can be re binded in game using the 1-0 keys
to restore it, go to your hero abilities menu. hover the mouse over the option you want binded and then hold the desired 1-0 key
