Points to Grid creates an uncomplete layer

[DimEvil]

Both in the ALA (and our Flemish version) the point to grid function creates a similar faulty map. An uncomplete raster map (only one vertical band?) was created

Flanders
Tools points to grid
-> extend 'Flanders'
-> Lifeform Birds
-> points to Grid -> Grid cell size 0.05 --> produce occurrence density layer

Australia
Tools points to grid
-> extend 'My rectangle'
-> Lifeform Birds
-> points to Grid -> Grid cell size 0.05 --> produce occurrence density layer
