Custom Groups don't show in order

I have Custom Groups, but they don’t show in the correct order when viewing our portfolios. Does anyone know how we can order our Custom Groups? At least alphabetically?

My Custom Groups are simply:

  • Portfolio A
  • Portfolio B
  • Portfolio C
    They are also in that order when managing the Custom Groups page.

When I view them in any portfolio though, they show in the order of B → C → A.
It’s not alphabetical, so I think it’s ordering them based on the number of investments under each portfolio. Seems an odd way to order them.

Does anyone else’s Custom Groups order themselves differently from what they have set by dragging them in the Custom Groups page?
