Tag Properties not coming through on Click to Graph

I just set up the Click to Graph on a project, I used it to replace an existing trending set up where I ran a script (on an Easy Chart) to return: Min,Max,Avg,StDev,Correlation,Total,Division.
For the Total column I ran an If/Else based on the Documentation properties of a tag (to determine if the tag was rate/hr or and actual incremental value). However, since implementing the CTG module, the tags documentation properties are no longer coming through. Nor are the engineering units, or tooltips.
The values so not show up on the y axis of the easy chart either.

All the above worked fine on the previous easy chart set up.

Any ideas what I could be missing?
