Debursting of merged products - error

Dear SNAP developpers,

I recently met issues while trying to deburst a set of merged images.

I face no issue debursting an intererogram. However, if I merge the said interferogram with other results that are geometrically equivalent, I cannot perform the debursting.

Here’s the operator node with sources that lead to the problem (Type : operatorException):

Is there any workaround ? Technically, there should not be any issue with that. The ensemble of images are perfectly coherent with the SAR products. Is it possible to modify slightly the file by commenting some lines to make it work ?
