Hello! 
I’m having trouble using ‘Split Brep Multiple’ correctly. I believed I could split my solids using one solid with two surfaces, expecting to get three breps as a result.
However, the outcome didn’t yield three breps. Can you help me understand where I might be making a mistake?

the data structure of your breps and the one of your cutters do not match:
if you flatten+reverse then graft the Breps, you’ll see that many of them gets cut into 2 parts:
that happens because your cutters on one side are tangent to the breps
if -just for the sake of trying- scale the breps in such a way they become bigger, you can confirm those are cut into 3 parts by the respective cutters, as you correctly believed 
[edit: I just recalled R8 has a new Volume component, I’m using R8, so -if you aren’t- I guess you’ll have to replace it with the R7 one to see the last example at work]
