Problem calculating span of coregistered images


I would like to calculate the span of my ALOS-2 Images after coregistration. It is no problem to calculate it using the original images but when I try to use my coregistered stack, I get the following error:
org.esa.snap.core.gpf.OperatorException: No enum constant org.csa.rstb.polarimetric.gpf.PolarimetricParametersOp.BandType.Span_09May2016

Applying decompositions is no problem with the stack. Does anyone know the reason for it?

Thank you very much.

Looks like a bug. What’s the input to the polarimetricParameters? Is it a stack of T3 or a stack of quad pol SLC?

It’s a stack of T3, as a polarimetric speckle filter was already applied to the images before coregistration.
