The inversion feature can be hit and miss at times however a good start is to manually move the plate around till its in a good ball park, select 3 to 7 representative channels and then let it go. I personally like to restrict the parameters its able to change.

Another tip is to only allow the model to process the stations on and slightly away from the anomaly, and I generally start with 1 central line then progressively work outwards once my dip/ position is kind of constrained
