Problem with location shortcode

hi i have a problem, with the shortcode location, it no show the map with determinate data. For example

[location coordinates="27.993974,-15.375731"]

In the last way not work but if i invert as next

[location coordinates="-15.375731,27.993974"]

it work, but not show the current location. When it not show bring me a message like the shortcode not build or something like that. The location i try is in Canarian Island, i test in others regions like US and work fine. What i doing wrong or i find a bug into the plugins?
