The Dev is probably going to need you to give more info about what you're seeing "wrong" with auto wave: Wave calls are designed to temporarily disable when there are still enemies remaining alive from more than a certain number of waves ago. Also, auto wave call has two possible modes (see settings). If 'instant' auto call is disabled, the next wave will not be called until the prior wave is entirely defeated. If the problem you're seeing isn't attributable to these explanations, you should add a note describing the details of what you see.
