Issue with the BandSelect Operator

In our efforts to migrate our processing GRAPHS we have stumbled upon another another issue that seems to effect the BandSelect operator. After several processing steps applied via GPT we want to write only a subset of the bands in the resulting product to a file. In the older version we were able to do this by using the BandSelect Operator just before a WRITE. However, doing this in the new version does not seem to have any effect and just all bands are written to the file nonetheless. We have also tried to do it via the GUI and there indeed we get an error in the graph-builder:

BandSelect: The Product ‘TestProduct_3’ already contains a band with the name ‘lat’.

But it does not make any sense. We do indeed have a band in our product called “lat” but why should the BandSelect operator care about this and throw an error? Any help would be very much appreciated!

Best regards,
