I am trying to check the enhanced seatmap for Eco and Biz on LX38 for April 21 or 22. Both requests keep coming up with the error "Unable to find a matching flight, or the flight is currently not available for sale in the requested Cabin Class [2]" while normal seat maps work fine. Headed over to expertflyer to take a look at the seatmap and there it shows the info, including blocks etc.

Can this be fixed?
