The mix of left-to-right and right-to-left script is often making issues with the copy-pastes.
I removed the latin text and the '!' because it was also making issues (which is weird because it's a right-to-left '!'. I have no idea...
Try to use the following to format:
-select by clicking on the left of the fourth line and drag up to the first line; copy/paste, do your alignment to the right, and THEN put the '!' back (at the end (left) of the 3d line).
I hope that works!
