In spec, equation 8-523 and 8-524 define top-left subblock position for subblock temporal merging candidate.
In SW, position for subblock temporal merging canddiate is defined as center position of subblock.

Equation 8-523 and 8-524 should be change as bellow

– The luma location ( xSb, ySb ) specifying the center sample of the current coding subblock relative to the top left luma sample of the current picture is derived as follows:
xSb = xCb + xSbIdx * sbWidth + (sbWidth >> 1) (8 523)
ySb = yCb + ySbIdx * sbHeight + (sbHeight >>1) (8 524)
