Expose filter is not working

In general please don't expect that people answer on all your issues immediately. Just look at the pure amount of new issues which views gets every day.

And then you write a question which is quite hard to understand, some simple english sentences though would have helped help.

One thing you can always do is to provide an export of the view, this explains us at least what you did.

 When order by selection menu has one option, it is not sorting if I add another order element to expose select menu, it works fine. could you help me what have I done wrong? or it's a bug Thanks in advance

My engrish converter says you have some sorts exported? Once you have just a single sort criteria you are not able to export things.

Actually my native language is not english :)

You export the view to code, to share the view with others, see screenshot. This allows people to understand what you did.

So here is a summary what i think you talk about.
You have basically multiple sorts on the page, the first one is sorting by date, the second one is sorting by price.
The second one can be changed by the user. The expected results is that the second sort, defined by the user, will be used instead of the date sort, but the actual result is in the order of the views ui. So it's still sorting by date first, and then by price either DESC or ASC.
