Store Locator PLus Error

I am using the pro version of the plugin. Having difficulties in adding the stores. Have added around 200 stores. When adding or modifying them it says
“Store Locator Plus needs attention:
Location #224 : Could not set the latitude and/or longitude”

and these stores dont show up on when i search them in the search field provided by the plugin.

Also on click of each store I want it to zoom into the store. How can I achieve this
