Hey Tim,
If that’s the case, it is most likely just grabbing the raw value. Unfortunately this makes it more difficult for us to modify the output if this is all managed via settings within their plugin.
You can try reaching out to the team at Essential Grid and see if they have any filters in place that would allow you to target the output of the meta that is pulled in. If so, we would be able to modify that value and format at using those filters.
Let me know what you find.
Thanks!
