SMT32CubeMX Can-Setup STM32F446 Auto Retransmit Flag mismatch between Cube and generated code

In CubeMX the name for the Automatic Retransmission of CAN-Messages is named:

"NO-AUTOMATIC Retransmission"and is set to "DISABLE"

When reading this I interpreted it as: Automatic Retransmission is done if set to DISABLE

In the generated code however the corresponding setting is:

hcan1.Init.AutoRetransmission = DISABLE;

Which leads to "no Automatic retransmission" and therefore to missing messages in case of high busload !!!

Please correct the wording in STMCubeMX so other users are not falling into the same problem.

I am already using Version 6.2.0!

However the project was created with FW_F4 V1.24.1. The missing CAN messages were detected now after the project is released to customers already.

Ok, and after updating the HAL release FW_F4 V1.24.1 to V. 1.26.0 the wording now is correct.

I am always careful when changing to new releases of HAL, because I encounter too often that problems arise with new releases which I often can't see in the fist place...

Did not think the HAL release would change the behaviour of Cube Setup menu entries...

Thank you for the support.
