Strange crop of the image after processing it with Biophysical Processor

Dear all,

I am testing the Biophysical Processor and I have found this strange behaviour while processing the 31SBD granule. I don´t have this behaviour while processing other granules:

The first image is an RGB view of the 31SBD granule at its original size and the second one is an image of the estimated LAI of the same granule. You can notice the black frame that crops the image.

The problem appears in the following bands:

and does not appear in:

Any idea about this problem?
