How to connect UDT with DB?

How connect UDT with DB? Anybody can help? 

 First you assign a variable name, then you write the UDT name to "Data type" column.

Ok, That is very clear and easy.

Problem is next. I download official SIEMENS library from this link: 

https://support.industry.siemens.com/cs/us/en/view/66839614 

And I'm connect everything like is described in library documentation. In HMI tags for MOTOR blok I have one tag with  UDT Data type which is from this official library. 

This UDT (Motor_UDTV 1.0.0) is connected to DB of block motor.

Official HMI screens from library are by default settings of SIEMENS, connect to MOTOR block via, this one tag and this "Motor_UDTV 1.0.0" data type.

But what happend on block, in OB, not come to HMI screen in during RunTime. And if I click on any buttom will not come to block, via this official UDT.

What I miss? What I must do more to connect HMI screens to block in OB, via this official UDT?

Everything else can normaly flow between PLC and HMI, except tag with this official UDT.

Is possible that problem is in Library?  Because source of library was V13 version (.ap13 extension), but I use TIA Portal V15, and I had to convert the file to version V15. Maybe conversion in TIA Portal cause this problem?
