Sort columns in board using mixed objects / workflows

Use case : I want to build a board mixing two different objects, each with their own workflow. Those workflows are sequential, ie Type A has 3 statuses and Type B 3 others. It’s useful for example if you want to visualize both a problem solving + solution implementation workflow
I set up those workflows using numbers at the beginning
Type A

  1. Step 1
  2. Step 2
  3. Step 3

Type B
4. Step 1

When I set up the board, use the workflow as columns and sort the columns by name ascending, the order of columns is not respected by fibery.
