Show font previews in english

My font previews are showing in Arabic, I believe, I can’t read it. I’ve tried setting everything to English (USA) but can’t fix it.

This question has escaped being answered, it appears. This enquiry is being re-asked approx 1-1/2 years later.
I am using LibreWriter 4.2. The font preview option displays all fonts in what appears to be Arabic.
Question: Is there a standard method to display the fonts in English? Or is this a “bug”?
