You can not look at corrections in fluent but you know what the corrections are in fluent. I said Min + Mout + Nfaces x Correction = 0;
(Min is negative in sign as V dot Area is negative here)

Pressure correction equations requires mass imbalance. So the outlet flux is corrected just before it and pressure correction source is built from corrected flux.

Flux correction after pressure...
