Google maps not "zooming" in Events+

It seems like the google maps interface in my Events+ isn't zooming at all. I've tried to change the settings in Events+ and in Google Maps.
I'm not trying to be difficult here, but I have encountered a lot of difficulty with these plugins. I was really sure that these would be the answer for my needs but between the difficulties I'm having where I check boxes and nothing changes and the lack of responsiveness of the elements I'm not sure that I can make it work.
