When I edit a location it isn’t possible to select a map marker (at the bottom of the page). When I want to select another marker I have to enter the correct complete URL (like this: /wp-content/plugins/store-locator-le/images/icons/bulb_azure.png for that marker to get it active and visible. This problem has been around for several versions now and is very annoying. I’ve tried it in Safari, Firefox and Chrome, all on an iMac with Mac OS High Sierra.
Also, there are always two or three scrollbars when editing or adding a location and it’s very difficult to scroll down to change settings because of that. This problem has always been around in all versions and also very annoying.
