store credits won’t turn off

Hi,
I don’t use store credits and I want them gone. Unfortunately I’m not able to turn them off. Whenever I try to disable the store credits module I get an error message that reads “failed to update” – and nothing changes. I get the same result when I try to hide zero balance. Even though the switch looks as it was off, when I refresh the page it is back on. Anybody knows how to deal with it?
