Land-sea mask not work - error point to a non-exist virtual band

I was trying to use the ‘Land-Sea-Mask’ 'to extract Water and Land using user defined vector, but get some error point to a non-exist virtual band as below:

The virtual bands are already converted into real band, so not sure why they are still there in the list.

Tried with both desktop (windows) and gpt (linux), neither one works.

But before II do got some successful run when using the SRTM (by default option) with an earlier version of SNAP.

Thanks,
Wenli
