I am new to Reefmaster and I am just completing my first lake mapping project. All looking good until I export to Google Earth Pro. I now have a yellow line around the shoreline. I have removed the shoreline in project/maps but it appears when exported.
Can anyone help please?

Can you show a picture of the map, both within RM and GE? You should be able to style the map in any way you want, so if the yellow outline is the shoreline you can either hide or delete it using the layers tab. You don't have both the old and new maps showing in GE at the same time by any chance?

Yes, silly me - old and new map at the same time doh!
