UM3292 wrong pin number for D14 on Arduino connector

Hi. I discovered an issue on UM3292 while trying to get PCF8574 I2C LCD module to work with my STM32U083C-DK. On page 22, it is stated that D14 is connected to PB9. However, it is actually connected to PB7. I have the MB1933C version. When I replaced PB9 with PB7 my code it works flawlessly.
