I imported your survey and tested it on a smartphone and I can reproduce the issue with the view of the survey on a mobile phone.

In the English version the responsive survey design kicks in, but in the Hebrew and Arabic view the survey gets displayed like a desktop layout, but very small and very much hidden to the right.

However, what is weird is that the structure of your survey doesn't show me any question group, which afaik is impossible. So there seems to be something fundamentally wrong with your survey structure.

Also, I can see that you have questions with a lot of Javascript, which might cause the issue.

Also weird: In the survey settings (this might be an error in LS6 the option for "group by group" exists twice.

Now, when I switch your survey to question by question, the mobile responsive view kicks in also for arabic (and I assume hebrew).

So this seems to have to do with the scripts that you are using in your survey.

The script is designed to create dropdown selection in array.
The script does not affect the display in the English language, but it does affect the Hebrew and Arabic RTL.
In my opinion, this is a design error and not because of the script

In my opinion, this is a design error and not because of the script.

Not really. The script is nothing provided by Limesurvey, but by a third party. So if Limesurvey works with its standard functions the way it is supposed to be, I wouldn't necessarily consider this a design error or bug of Limesurvey, but rather an issue with the script.

Maybe the script does not work well with RTL languages and needs to be adapted.

Attached lss without java script .
same error
