There are several shade control modules on your coach. Each module controls 4 windows and 8 shades (4 day, 4 night) and is networked via the RV-C network. I suspect you have either a bad shade module or it has a broken power or network connection.
Don't know where they all are on your coach. I do know there is one over the entry door but that one controls shades in the front of the coach. A good bet is some of the others may be in the bathroom somewhere.
See page 26 of
this document for troubleshooting help.
Call firefly if you can't find them, they should be able to tell you.
Here's a picture of what it looks like, this photo is from a 2016 DLQ over the entry door:
Good luck!
