377	On merge data syntax	chhuanb		"In current merge data syntax, if sps_mmvd_enabled_flag is false, merge_idx for regular merge mode will not be parsed, as follow:

'''7.3.8.7	Merge data syntax'''

merge_data( x0, y0, cbWidth, cbHeight, chType ) {
...
			if ( regular_merge_flag[ x0 ][ y0 ] = = 1 ){
				if( sps_mmvd_enabled_flag ) {
					mmvd_merge_flag[ x0 ][ y0 ]
					if( mmvd_merge_flag[ x0 ][ y0 ] = = 1 ) {
						if( MaxNumMergeCand > 1 )
							mmvd_cand_flag[ x0 ][ y0 ]
						mmvd_distance_idx[ x0 ][ y0 ]
						mmvd_direction_idx[ x0 ][ y0 ]
					} else {
						if( MaxNumMergeCand > 1 )

Should be:

'''7.3.8.7	Merge data syntax'''

merge_data( x0, y0, cbWidth, cbHeight, chType ) {
...
			if ( regular_merge_flag[ x0 ][ y0 ] = = 1 ){
				if( sps_mmvd_enabled_flag )
					mmvd_merge_flag[ x0 ][ y0 ]
				if( mmvd_merge_flag[ x0 ][ y0 ] = = 1 ) {
					if( MaxNumMergeCand > 1 )
						mmvd_cand_flag[ x0 ][ y0 ]
					mmvd_distance_idx[ x0 ][ y0 ]
					mmvd_direction_idx[ x0 ][ y0 ]
				} else {
					if( MaxNumMergeCand > 1 )
						merge_idx[ x0 ][ y0 ]
				}
