Have you selected or uploaded custom icons for your places via the ‘Maps and Markers’ section, but they’re not showing up on the map?

Make sure you have turned off ‘Numbering’. By default, the places are numbered in sequential order, so you will need to turn this off in order for your icons to be displayed instead.

Under the ‘Plot Locations’ section, click on the ‘Numbering:ON/OFF’

Then toggle to ‘Unnumbered’. Publish your map.
