Garmin Oregon 600 Display Color

I have had an Oregon 600 for years now and have loaded many different maps on it. I've never had this issue before.

I downloaded this Minnesota topo map from here:

Code:

gpsfiledepot.com/maps/view/153/

It shows all good on basecamp (Mac). When I load it to my GPS though, the water is all grey color (same as surrounding area) with a red outline. So it is very, very hard to see rivers and lakes. I am going canoeing at the Boundary Waters, so this is a pretty big issue.

Does anyone know why this would happen? Or how to get around it? Any pointers? Or even just have another map I can use instead?

Thanks!!!

 

Thanks @Nuvi-Nebie . Unfortunately not having any luck with that. You can see what it looks like at the image attached. I suspect it may be the map itself, but not certain.
