Anthony,
You make a really good point. They should come with a Lower Third on the right and left.
The only way I know how to do it is the old fashioned way. Luckily with Lower Thirds like the Weave-Lower-Third the text and lower third are in separate groups. In this case, select the “Arrows” group and change it’s Y rotation 180 degrees. That will put it on the other side. Then move the text. Hope this helps and best of luck.
