Loading Icon keeps showing for Post Global Map

Hi There,

The loading icon keeps showing when a specific zoom option is specified. Please see here

Whereas this is not an issue only when using auto zoom option.

However I would much rather be able to specify the zoom level of the map for each form. Is there a way to fix this?
Thanks.

Regards,
Sherry
