Why gets the SPI DMA configuration lost when re-opening *.ioc with CubeMX (STM32MP1)?

[JMein.1]

My problem is, that on the one hand, the SPI3 configuration is lost after I close CubeMX.

1. The assignment is lost to the M4 core (changed from A7 to M4 and after reopening, its again at A7. The changes have been saved and tried on different machines).
2. If the assignment of the DMA streams for the peripherals has been done, after reopening CubeMx and *ioc file, the DMA streams differ or are completely lost.

So, what I am doing wrong here? Is there maybe another problem with the GPIO or whatever, which can lead to this unexpected behaviour? Or is this a known issue?

Thank you for the help.

Best regards,

Jan-Otto
