what is happening here? in picture B?

Uhh .. without any further context than what is shown on those two pics, I’d guess that the top one, due to the splitter right before the 90 degree turn, is only getting half the stuff.

The bottom one looks fully backed up.

I’d say that’s why they don’t look the same. But again, that’s without having further context.

Not familiar with the mod(s) used, too, so in theory it could also be something to do with that, too? I don’t know.

Either that or the belt was full and you manually rotated it, leading to overcompression until it gets un-backed up.

Hard to say without knowing what specifically you're referring to.
