StaMPS export does not work with TopoPhaseRemoval

Dear Luis,
Thank you very much for all your efforts! Now we have a bridge from SNAP to PSI which is really very important for processing S-1 images! It is great!
At present the problem is that StaMPS export does not work after TopoPhaseRemoval functionality. It works with just differential ifgs (interferogram funcionality) but when we add TopoPhaseRemoval to our graph we get errors. And for StaMPS we need ifgs with subtracted dem. Could you, please, give an advise how to overcome this?
Thank you again
