Change alignment for RTL Text Labels

Hi there. I have a Storyline 2 course in Arabic. We are using the Arabic text labels built in to the player. But when the course is played, those default text labels are not right-aligned in the pop-up boxes, such as for the text label for Invalid Answer Text (#22 label).

Is there a way to edit those text labels so they read right to left and right-aligned in the pop up box? Yes, we've checked that box in the "Other" screen. Perhaps after publishing the course to LMS, there is a .js file or xml file that could be edited to make the text read right to left/right aligned?

Thanks!
