Multiple taxonomy terms per page get tracked as one term with commas

Under the “Basic Data” tab of the plugin settings, I checked “Post Terms.” Likewise, in my data layer, I am seeing something like the following:

{
pagePostTerms: {grade: [“6″,”7″,”8”], subject: [“Math”,”Science”]}
}

As you can see, I have a couple of custom taxonomies, and my WordPress posts can have multiple terms applied from the same taxonomy. I want these taxonomy terms tracked as separate content groups.

So I set up a Google Tag Manager (GTM) data layer variable called customGroupGrades, and in that variable’s settings, for the data layer variable name, I entered the following based on the data layer snippet shown above.

pagePostTerms.grade

Then, in my universal GA tag settings, I added a content group and set the value to this new data layer variable.

As a result, an array of taxonomy terms (grades) are being specified as the content group. I was hoping that the Google Analytics content group would interpret this array as multiple groups. But instead it interprets it as one group named “3,4,5,6” and so on.

Is there a way that I can track a custom taxonomy’s terms as content groups so that one page can be in multiple groups? Google says this is possible, but I can’t find a detailed example of how to do this.
