SNK1M1 missing PDOs

I have build the SNK1M1 project directly from github. For some reason it is missing PDOs. As a result there are several things I am not capable of doing.

Any idea why this is not showing PDOs in the STM32CubeMonitor panel?

Next to VDM SOP there should be a tab for the PDOs but its missing. Seems that the source is built with the expectation that there will be PDOs. The SNK1M1 itself does not seem to have PDOs even if I add some with the MX configuration they still do not appear.

I managed to get this issue solved by flashing the provided binary. I guess something is wrong with the source.
