You cannot group by fields that contain {% data variables.product.company_short %} data (such as: title, assignees, repository, labels, milestone). When items are grouped, if you drag an item to a new group, the value of that group is applied. For example, if you group by `Status` and then drag an item with a status of `In progress` to the `Done` group, the status of the item will switch to `Done`.
