Please ignore my last email, this is not the case, I had vectors with similar names in the current mapset. Sorry for confusion. Still struggling on this.

OK it took me some time but I think I figured things out. The problem was the weird topology of the input vector file (created outside grass by another person). One record in the table would correspond to more than one polygons, and this somehow created problems. I solved exporting the vector to geopackage and then import again and I got a much longer table associated, now one record per polygon.
Thanks
