When configuring the Advanced Properties of a LabTutor Data Panel in LabAuthor, why do I get an error if I check the 'Channel Controls' checkbox?

The Channel Controls option in the Advanced properties of a Data Panel are only utilised when using the Channel Overlay Display Mode. This option is still available when other Display Modes are selected, but will produce the described error if the Display Mode selected is not 'Channel Overlay':
servlet.ImageServer?id=015w0000001JLNf&oid=00D20000000HncM

The Display Mode here is set to 'Record Overlay' - since it is not 'Channel Overlay', the error occurs
