For a well that is inside the model grid the well head indexes I and J (in WELSPECS) are set to I and J of the first cell of the well (I and J from first entry of COMPDAT). In case when a well is outside of the grid, the well is reduced to a single cell and shut in the first cell of the model.
However in case of a multilateral well if the main leg is outside of the grid, then well heads for all the legs are set to the first cell, including the ones that are in the grid, example of generated .SCH files where legs Y1 (main) and Y3 are outside of the grid and Y2 is inside and yet I and J are set to 1 and 1 for Y2:

Possible solution is to set I and J in WELSPECS for WELL_Y2 to the first entry of the COMPDAT for that leg. In above example this would be 33 and 50). Or default well head with 1* and 1* which should then default to first entry in COMPDAT.
