The graphs work fine but I never used to get this error. BE, any suggestions?
It's not really an error, more of a warning.
I can't turn those messages off though.
It usually means that one or more of the graphs have no data.
That quite often happens when Interleaving is turned on/off. From that point onward some of the graphs may or may not be relevant, so no data will be present.
Could that fit with the issue/warning messages you are seeing?
A lack of data is usually a GOOD sign?
