Arabic text formatting in Storyline 360

Hi,

We are working on an Arabic course in Storyline but are experiencing a lot of text formatting errors. We have used the same font throughout the course (Gotham Book) but it is displaying inconsistently throughout. The Arabic script formats correctly about 90% of the time, but the rest of the time, renders incorrectly. This is only obvious in the exported files and not in preview mode in Storyline. For example, in the screenshot attached, the first image has been distorted from a number to something like “ISORY”, and in the second screenshot, random “Cs” seem to have appeared.

If you have any suggestion as to how we can fix these formatting errors, it would be much appreciated.
