For making it clear, Transcy still supports to translate your Product Description into Arabic language with correct writting format "right to left", but the writing style "right to left" of Product Title or Variant has not yet supported because their writting format "right to left" is not supported by Shopify. Meantime, our technical dev is still checking on it to have a resolution in the near future.
Your product title is in English and it`s still supported to translate into Arabic language, but its writing style "right to left" has not been supported. However, its content is fully translated with correct writting format.
