In a Statistic Collector, when putting a string literal in the “Value” field of an Event Data Label on the Event Listening tab, the quotation marks are not removed from the value when logged in the Statistic Collector’s data.
For example, when the string literal “Transit” is returned, the quotation marks remain, whereas when using a method that returns a string (such as data.activity.name), this does not occur. I've attached an image of an extract of one of the columns of the Statistic Collector’s data as seen using “View Table”.
These quotation marks cause JSON parse errors when trying plot the output of the Statistic Collector on a graph. Here’s an example of a JSON parse error that is returned.
Callstack:

Not being able to return string literals in Statistic Collectors is very frustrating and counter-intuitive. I am running version 18.2.0 of FlexSim.
