have to keep re-adding AkBank to Unity project

Question

With respect to Unity-Wwise integration, my students and I keep getting errors in Unity saying "Event ID not found".  The events being called do in fact exist and the SoundBank has been properly generated.  The only solution that seems to work consistently is to delete the AkBank component from the WwiseGlobal gameObject and add it again.  In some cases, this must be done every time a change is made to the Wwise project, which of course gets pretty annoying after awhile.

Any ideas why this is happening?  Any suggestions on how to resolve it?
