I noticed that there seems to be a limitation in the elements (and their values) that can appear in the dashboard.
as seen in the screenshot below, some elements cannot be represented in lines, and some of the elements do not report their actual values, when exported as csv from the table (the values appear as undefined).
upon further inspection, these are 2 elements that do not belong in the Revit categories. so it seems that the issue is not a limitation, just some other entity (perhaps cameras?)
