Using Format function with Calculated Groups to convert numbers to millions doesn't work properly

[Yonko]

Hello. I have some data with big numbers and what i want is to create a slicer so a user can choose what format he want to see: usual (like 1 234 567) or in millions (1.2 M). To make this i created a calculation group with two values - first one is nothing but a SELECTEDMEASURE() and the second one is FORMAT function (you can see it on screen).
The problem that when i activate Mln option on slicer it works only with card or table visual but don't work with line or bar chart. I guess the problem may be because it convers it to text format and it can't calculate it properly or something else. Anyway, any suggestions to force it work on every visual?

Without applying format:

With format:

Change the calculation item for the millions. Change the expression to just return SELECTEDMEASURE(), as the other one does, and instead edit the format string expression for the millions.
