I've recently updated to the version of 22x with the Element Redaction Tool (from base 22x) and am having an issue where my Data Markings are always seen as not redacted (green) even when previewing or transforming with that Data Marking. Previously I had used the PLE variant realization transformation to perform this element redaction and have tried to transition to the new Element Redaction Tool without entirely recreating the Data Markings that I have (as some are in use by programs and would have to reapply all markings). 

Is there documentation to better understand how the "com.nomagic.magicdraw.datamarkingsandclassification.expression.DataMarkingExpression" script works? That is applied on the ExistenceVariationPoints but it is unclear how it is functioning and if it is somehow getting flipped around somewhere (where redacted becomes not-redacted).

Here is an example but it doesn't show much.
