Custom period for reports and playback

I can't insert custom period for reports when i use arabic language (version 5.1 and 5.2)
In English language I have no problem

Please provide more details about the problem. Also ideally file a bug report on Github.

thank you Anton

When the date is selected, the date and time box remains blank and no response occurs
And when I enter the date and time manually, it returns to the situation as in the above picture. It gives the following error:

Text 'null' could not be parsed at index 0 - DateTimeParseException (... < DateUtil:63 < DateParameterConverterProvider:32 < *:28 < ...)

Can you include a screenshot?

I uploaded a video to YouTube, is it allowed to share the link here?

Yes, you can share a link.

You need to recompile the web app. Or wait for the next official release.
