Checking input values

https://wordpress.org/support/topic/default-settings-overriding/:

I input the basic shortcode e.g [leaflet-map lat=53.10902942035064 lng=-7.723388671875001 zoom=7] and the map only shows at the default lat and long, but the zoom value overrides the default settings. Leaving default settings blank leads to no map loading. What is the issue here? Thank you in advance!

You need to check the input in settings page, some settings must not be empty.

Going on vacation for a couple weeks so I won't be able to have a good look until then. Thanks
