Orange3B, UART9 pinout confusion (wrong in datasheet and manual)

Hi,
we are trying to use raspberry hat with 3xUART on orange 3B board.
On the official page UART9 uses pins 7(TX) and 29(RX) of GPIO header (40pins) which is compartible with Rpi.
However finally it turns out that TX not on pin 7 but on pin 22.

At orange3B wiki page there two different confusing screenshots (the are below) regarding the piout.
In one TX is on pin 7 on other on pin 22.

Could you please help to understand how to configure pins to use in 7 as TX for UART9?
