STM32CubeMX 4.25 wrong pin labels / positions STM32L433RCTx

Hi guys.

I'm working on a STM32L433RCTP based project with STM32CubeMX.

It's probably not the best idea to use CubeMX as a reference, if you have the datasheet / ref manual....

It took some hours for me to figure out, why there are some pins not responding to what I've done with them. Here is the reason: I located the pins by looking at the CubeMX drawing. But in STM32CubeMX there are some pins wrong.

I took two screenshots. On the right side, there is a screenshot from the datasheet and on the left side you can see a screenshot from CubeMX. The CubeMX screenshot is overlayed by the pin names, extracted from the datasheet screener. So you can compare the pins in CubeMX with the pins in the datasheet.

As you can see, the pins in the red boxes doesn't match with the ones from the datasheet.

However, the generated code and the pin functionality seems to be working.

I wonder if this is an issue for other controllers, too.

It is not a STM32CubeMx problem.

You chose the wrong device in 

STM32CubeMx. There are 2 different devices with reference 'STM32L433RC': STM32L433RCTx and STM32L433RCTxP. Acording to your post, you are using the 

STM32L433RCTP reference. But you screenshot shows me you selected STM32L433RCTx option in the STM32CubeMx software.
