Ronaldo Element - Align Right Doesn't working on Heading 2 & Span

I am trying to move then to the right side because of my RTL language and the Heading 2 & Span are not responding to the right align.

What could be the problem?

Parent settings of flex are aligning that to the left. You can select a parent, and set to be aligned to the right side. You will see setting for “Horizontal” and click last icon (flex-end).
