Selecting PLL3R for ADC clock in STM32CubeIDE. Possible bug

[fbar]

I cannot set PLL3R using STM32CubeIDE when working on a Nucleo-H743ZI2 board. Using STM32CubeMX with the same updated firmware, there's no problem selecting PLL3R

After I create a project with STM32CubeMX selecting PLL3R and select STM32CubeIDE as the toolchain, I can then open it in STM32CubeMX and change settings for PLL3, which are reflected in the ADC clock box. But as soon as I click PLL2P, I cannot re-select PLL3R anymore.

If I reopen that same *.ioc file in STM32CubeMX again, I can switch from PLL2P to PLL3R without problems. And if I save it and reopen it in STM32CubeIDE, PLL3R is properly selected and everything works.

Looks like a bug to me...
