Mobile Application Builder Version Error

Hello, I am trying to build first mobile application. But, it gives an error on version field. Whether it is filled or empty , i meet with the same error. And additionaly, I can not see what is the problem, what is the error, only error field is opened and empty error message is given.
I attached the screen about it.

Hello, huseyin temur!

Due to Apple policy, the application version should contain 3 numbers, separated with dots, for example 1.0.1, so you need to change the application to match this mask.

Hello, I changed version field to 1.0.1 then it gives an error about mobile application platform version. I attached the error. So , what should I do then? What do I need to change?

Hello, What changes do I need to do? Can you explain more please? Thank you in advance.

Sorry, you need to change the application version, you have this field highlighted on the first screenshot. Type 1.0.1 there.

Hello, I changed there and I saved and post the related document. But , then I need to build this document, so I try to build the document and it gives the last error. I was talking about this at the last print screen.

Regarding the second screenshot, you need to upload the new mobile platform version to the mobile application builder. See the attached screenshot for details on how to do this.

Enter 3.4.5 is OK
