Steps to reproduce the behavior

Click on a radiobutton
You can see 2 radiobutton checked (the one you check and the same radiobutton on the other formarray)

Expected behavior

Click on a radiobutton
You can see 1 radiobutton checked (the one you check and the same radiobutton on the other formarray is not checked)

It seems to be a bug and even if both are checked in UI and checked="true", when I check value in TS, just one is set...
