A favorite list, depending on how it's created may have several sites that are out of your are.
You can create by "Add channels on range" which for me in Ohio seems to add sites for the entire state.
You can also click on a section and add to the favorite.
If you are using this at a fixed location you can delete (or avoid) the sites that are out of range.
Example: I use one favorite exclusively ay home, no location based scanning needed and I have limited it to 2 sites.
Tip - if you are using a favorite with no location info. which is the default range can be anything, it has no bearing.
As to the original question, not sure why some are red. On my most used favorite with 2 sites both are grey.
I'm not sure if this is true on a Favorite with location off.
Gray sites indicate sites enabled by range. Red sites indicate sites disabled by range. Orange sites are avoided sites
