Why do LabTutor data panels appear live in LabAuthor, but are grayed out when installed on LabTutor Server?

Many of the features available in a LabTutor experiment will be bypassed when viewed in LabAuthor.
LabTutor Data Panels with the "Allow data changes" box unchecked, will activate and appear live in LabAuthor. This is so example data may be added while in author mode. These will be deactivated when the experiment is installed on the server.  Please check the LabTutor data panel properties dialog to ensure the "Allow data changes" box is checked on all data panels where students will need to record data before saving the experiment and experiment installer.

Other elements that have different functionality when viewed in Author mode include checkpoints which will not appear active, and all email and submit options from report pages are inactive until installed on server.
