Location marker and search form not working

We have created a Google API key with an associated billing account and while the map loads on the page, the search function does nothing and there is no marker for the starting location or the single business location we have created even though we have selected to Auto-load all locations. Not sure what is going on as we have used this plugin on other sites in the past with no problem. Thoughts?

One odd thing is that there is a note in red that reads “You have too many locations to auto-load them all. Only the closest 250 will be displayed if auto-load all is selected.” but we only have one location.

Thank you!
