Hi is there an issue with the group sorting logic?
It seems to be behaving the opposite for my virtual column [isCertified] (“Pending”, “Certified”). It’s a “Yes/No” type column, with Pending for FALSE, and Certified for TRUE.
I believe your assumption is correct. The sorting gets applied on the “ actual” field value rather than the “display” value.
I believe this is an edge case. In case of Y/N columns, display values were introduced a few years ago. However sorting is based on actual values like all other columns.
