Direction according to language (LTR + RTL)

Hi

I have just created a single post template in Bricksbuilder, I have posts in both Arabic and English (riyadhkey.com)

Now if I add a new post in English, it will align to Right (RTL), the old posts are also changed alignment to RTL, while Arabic posts are ok.

No if I go back to old default template, it behaves like the new one (RTL)

Please help
