Local CouchDB on Mac Opens New Browser Tab Every 5 Seconds

I am doing some testing with CouchDB. I downloaded the CouchDB application on my Mac and ran it - it opened in my browser, I verified, created a database, added docs ... then I closed the application. Next time I opened the CouchDB application, it opened a screen with the side menu but no other content (see attached image) and proceeds to open a new and identical tab every 5-10 seconds. The only way I can stop it is by closing the CouchDB application. Any ideas about what is going on here?
