Why resampling rants about different sizes?

I opened a single granule of an image, deleted all bands except the ones at 10 m resolution, and tried to resample.

SNAP rants about the bands having “different sizes”. How do the bands have different sizes, if they all are at 10m resolution?

Dear Cipa,

In order to replicate your issue, could you please report which is your OS and all the applied steps?
From my understanding:
-1) You opened a S2 granule
-2) You deleted all the bands except the ones at 10m
But:
-3) How did you obtain the Virtual Band [VerdeInfra]? Is it a combination between Green and Infra-Red bands?
-4) At which step did you get the “Resampled Required” message?

Thank you,

Regards,
Fabrizio
