How do you extract the name of Calculation Group Item so you can display what is chosen? Ie in the title of matrix or graph

It should be simple and follow this type of pattern.

VAR _SelectedItem = SELECTEDVALUE('CG_TI_All'[Period] , "No Selection")

RETURN
_SelectedItem

It only works for the first ordinal in a Calc group
For anything else I choose, it ‘disappears’, assume no value returned

FYI - I figured it out that i had multiple calc groups effecting measure in a title.
