Hey Ryan! Ack. It seems like there's a bug around custom columns + background color here. There is a not-great workaround to *not *use custom columns and instead, use JS transformer to add columns into your data object (after it comes in from your db).

Let me know if you have any questions or concerns about getting that workaround going! In general, it's actually best practice to avoid custom columns since they're entirely frontend.
