It seems that this Device doesn't have variables but it is not true


What is wrong with my device? When I try to create event, or derived variable, or rolling window variable i got this message: “It seems that this Device doesn’t have variables”. But my device have 6 variables which are reported in 15 minutes period. They are still active and presented on dashbord.
Best Regards
