Did you find a solution to this? I am having the same problem where not more than 1 marker is showing at a time on the live view, but it shows all markers on the admin/control panel.
Although it does just show one location of each different marker design. For example I may have 5 red markers, 5 green markers, etc … And it will only show 1 marker of each type.
Please need to know if I am doing something wrong or if this is a bug!!
