STM32CubeMX issue with STM32H7S3I8 DMA and TIM15_CH2

I have been working on an application with multiple DMA channels and timers.  For some reason, STM32CubeMX doesn't have the proper drop-down options for TIM15_CH2 in the DMA channel configuration. All the other timers and channels appear to configure properly:

Here is the generated code.  My fix/workaround is shown in RED, while the code generated by STM32CubeMX is in GREEN:

Luckily, we do have the work-around, but the problem has become relatively annoying.  Thank you in advance.

Hello @rbtmkr42 @and welcome to the ST Community.

Could you please add your .ioc file (based on the STM32CubeMX V6.14.1) so we can reproduce this on our side.

Best Regards.
