Email Routing: Activity Log does not match Email Routing summary

What is the issue you’re encountering

In Email Routing Overview screen, Activity Log does not match Email Routing summary

What are the steps to reproduce the issue?

When I check the Email Routing Overview screen, I see that Email Routing summary shows total emails received is 15, but only 1 email shows in the Activity Log. Why does the quantity in Activity Log not match Email Routing summary? Also of those 15 received, 9 were forwarded and 6 are marked as ‘Other’ - how can I determine what happened to the emails marked ‘Other’ if there is no info about them in Activity log?
