DVR receiver losing satellite configuration - DirecTV

I have several DVRS. One keeps losing it's satellite configuration everytime there is a power outage (there have been several in the last few months) or we have a rain or storm fade event. It is the only DVR receiver that does this and it is a fairly recent issue. It resets to a 3LNB config when it needs to be a 5LNB config.

It is model HR22-100.

Is this behavior a sign an issue with this particular receiver?
