Events+ will not show multiple categories

Shortcode for events calendar only works when showing one category. Specifying 2 categories shows 0 results. I have tried the slug as well as the numerical categories. I switched to theme 2016 with the same results.

[eab_calendar category="5" navigation="yes"] WORKS
[eab_calendar category="8" navigation="yes"] WORKS
[eab_calendar category="5,8" navigation="yes"] DOES NOT WORK, 0 results
