Hi, this is due to a change at 4428. Newer versions of Anki stabilizes the direction of cards.
Previous versions of Anki (your stable release) would render as shown in the beta version if you change the UI language from English to Arabic (or vice versa). Newer versions of Anki makes the direction stable, regardless of the UI language. The direction of the card is the same as the direction of the first letter in the card (in the question field).
If you need the direction of the card to be LTR you can insert a dummy English letter at the beginning of the question field.
