multiple markers make all “visible”

Hi, I’ve followed the shortcode helper to show multiple markers. For each marker I use this syntax:

[leaflet-marker visible Lng= “-2.2791315” Lat= “53.4426223”]venue id number: <a href=https://chorltonartsfestival.org/locations/venue>venue name</a>[/leaflet-marker] where the italicised text refers to the particular venue.

However, Only one marker shows and the label has a lot of unnecessary white space. Is there a way to a) make them all show by default (I will probably just use the id number to reduce clutter) and b) reduce the amount of white space when including a link?

Thanks
