1. Be sure you have matched the "active" region to the queried raster.
E.g.: "g.region rast=dem", perhaps with "-a" flag
2. Remove the MASK! Alternatively, if the MASK is big and takes a long
time to rebuild, just rename it temporarily for example with "g.rename
Then the points lying outside of the MASK should be updated as well.
Kind regards, Nikos
