Hi Anni,
I’m not sure what you mean, the navigation in Arabic version is in RTL, the logo is coming from the right, then navigation, then flag icons. And if it’s about navigation items, the Asiakkaat is coming from the right which is Customers in English version.
And the builder will follow the same direction, right to left (if you’re referring your right screen monitor as left, then it’s left to right which is still correct).
Could you clarify the issue you’re getting by providing visuals with arrows pointing to the issue?
And in padding issue, it must be changed manually to match the direction of the layout. If padding is added on left on English version, then it must be applied to right on Arabic version. And maybe the current options are confusing since Advanced mode is inactive. Please open you page in arabic and toggle on the Advanced mode.

And please remove the javascript, it’s incomplete and cut in the middle. It’s not gonna work.
Thanks!
