Events+ Calendar Navigation Skips a Whole Month

I've noticed a bug with the events calendar shortcode and the events calendar sidebar widget, when you click to view the next month, it skips to the following month.

For example, on my site http://uppermichiganmoose.com/pure-energy-fitness/

When I click to go to February from January, it takes me to March. I can click the back button to get to February but it's a real pain.

I imagine the developers are very busy, but this should be a simple fix.

Also, should I create separate support tickets for different requests?

Thanks in advance!
