Weird "nan" (presumably "not a number") in RGB info

I'm using (an older version of) Trapcode Particular to create some stars forming a logo. I've coloured the particles from a gradient ramp with completely normal (not over 1,1,1) colours, which range from a light cyan to white - no yellow at all. Weirdly, one clump of particles (I have no other effects on the layer other than Particular) renders as yellow, and if I look at its RGB values, the blue is "nan", which I've never seen before. My project is 32 bit, set to "Adobe Color Managed" (I also tried some of the OCIO options, but it made no difference to the Area of Weirdness):

If I drop the comp into my PPro timeline, the Area of Weirdness appears as a black dot:

If I change the project to 8bpc, the issue goes away. But my glows and sparkles aren't as nice.

 

Odd.

    Does it solve itself when switching the render engine to "Software only" or perhaps if it's set to that set it as whatever engine supported by your GPU? (CUDA, Metal, OpenCL) You can access those from the project settings.

     

    Would also be good to know if you see this issue only in the beta build or release version as well. And perhaps share your computer hardware details like CPU, GPU, GPU driver version (if not Mac)
