V12 report builder edit content on submittable doctype not possible

Dear colleagues,

we have a Sales Order doctype with a custom field, which is “allow on submit”. The value of this is edited after the sales order is submitted (to track status). This works fine in the form view. The team however has done this editing in their regular meeting in the report generator view.

It seems like it is no longer possible to edit contents in the report generator on a submittable doctype. Is this by design, a bug or am I missing a new configuration option?
