Custom format strings reset when you modify a measure formula

I create measure A, then use a custom format string to format it in the Model view.


When I change the DAX formula of measure A, its format goes back to some default format, and my custom format string is gone.


This is clearly an issue -- custom format strings must be preserved when modifying DAX formulas.

Would you please share detail steps for us to reproduce the issue?

  4. Go back to the Report view and change the formula of the Measure measure, for example like so (I just changed 1 to 2):
    Measure = 2
  5. Go to the Model view and note that the format has been reset to Whole number instead of Custom:
