Ability cast options won't save between sessions

[Testwamore]

Every time I get into the game I pick Vyper, I am getting ready to throw my instant cast venom on enemy, just to be presented with some weird select hero menu. I freak out and lose the kill. Then I go to the settings and set up instant cast again.

Happens to me every session.

TL/DR Abilities cast settings won't save between sessions.
