Data Labels and Formatting via calculation group

Hi everyone,

I stumbled across some weird behaviour concerning formatting via calculation items and data labels.

So I have a calculation group with two items

• "None" - applies nothing
  • Expression: SELECTEDMEASURE()
  • Format String Expression: SELECTEDMEASUREFORMATSTRING()
• "Formatted" - should format the number to millions with no decimal places:
  • Expression: SELECTEDMEASURE()
  • Format String Expression: "#,#0,,.M"

Now this calcualtion group does indeed work with e.g. tables but when I want to use this in data labels it does not work, instead it simply adds an "M" at the end of the value, without formatting the value:

Are data labels somehow calculated differently? Or could it simply be a bug because of the new features regarding dynamic data labels and such?

Perhaps someone here can shed some light!

Thank you 🙂
