Worked: (optional)

Short description of error
There is no way to turn off particles of spray or foam or bubbles. Particles turn off all at once. You cannot disable only one type of particle. I turn off the particles in the Particles tab.

Exact steps for others to reproduce the error
Bake this scene and bake the secondary particles. Try turning off the Spray particles.

I can disable the Spray Particles, but they are very similar to Foam Particles.

I don't know if it should be this way, but it doesn't look like the issue reported.
Can give us more clear instructions on how to reproduce it?

Open the mantaflow_bug_01.blend file
Bake FLIP particles with the "Bake Data" button
Bake secondary particles with the "Bake Particles" button
After these actions, secondary particle systems are created.
But these systems are exactly the same.
It is not possible to turn off only bubbles, spray or foam individually.
Since all these three types of particles are duplicated in each particle system.
I set the colors for different particles and saw the following:

As can be seen, all particle systems are identical:

Bubbles particles should be under water.
Spray particles should be above water.
Foam particles should be on the surface of the water.
