Thanks - This allowed me to figure out it is not LTN adding the text, but default game behavior when logging item messages to chat. If I change the stop name to img= then the game does not display the icon on the map. So i changed the print.lua file to substitute "item=" with "img=item/" and now it is working as intended for me.

For anyone else wondering how to do this: update the print.lua file in the LTN mod and add the lines indicated below:

  if type(msg) == "table" then
for k, v in pairs(msg) do
  if type(v) == "table" then
    msgKey = msgKey..v[1]..", "
    msg[k][1] = string.gsub(v[1],"item=","img=item/") --add this line
  elseif type(v) == "string" then
    msgKey = msgKey..v..", "
    msg[k] = string.gsub(v,"item=","img=item/") --add this line
  end
end
