Cannot get cc and moon to agree on file path name

Samsung tablet android 6. There is an Sd card but cc library is actually in main storage. Cc says the path to the books is storage /emulated/ 0/ cc.
Moon sees the path to the same books as ...sdcard/cc
I guess one is symbolic, one is actual but neither program will use the other path name convention.
Moon uses the path name when it adds a book to recent list, so I get duplicates if I open two different ways, because there are two equivalent ways to define the path.
ie to moon , ...sdcard/cc/book1 is not the same database entry as ...emulated/0/cc/ book1 even though both path formats lead to the same place
How can I fix this?
If I browse with moon to find the cc library and drill down from / (root) into /storage, then moon immediately changes the path descriptor to ...sdcard.
If I start with cc and try to define a library location, I cannot use sdcard as a path to internal storage because cc cannot see such a path option.
Is there a way to set up the library location so that they agree to use the same path name

On my fire tablet, android 5, no Sd card, I was able to get both to agree on using ...emulated/0... but I cannot get that to work on the Samsung.
