On the Route page of your FMC what is the altitude next to the waypoint? Is it the same as your cruizing altitude or is it higher?

Then some airways have an upper and lower limit. It is possible that the waypoint is only applicable to the route, therefore it has an upper and lower limit as well. Probably what the FMC is trying to tell you.
