Arabic captions won't display right to left

I've been localizing a course from English to Arabic, and I've come across a problem regarding the captions. I can't seem to have the captions display right to left, so the Arabic captions always display incorrectly. I did find a fix here:

It works, but its not a great solution, since I have manually alter the published file. Does anyone know how to convert the captions to right to left in Articulate? Or have a workable solution to have the Arabic display correctly?
