In JVET-P2001vC, when pt_present_flag[ i ] is equal to 0, i-th PTL's profile/tier/general constraints information can be inferred from (i-1)-th PTL's as below.

"""the profile, tier, and general constraints information for the i-th profile_tier_level( ) syntax structure in the VPS are inferred to be the same as that for the ( i − 1 )-th profile_tier_level( ) syntax structure in the VPS. """

However, 1st PTL cannot refer to 0-th PTL's profile/tier/general constraints information when pt_present_flag[1] is equal to 0, because pt_present_flag[0] of 0-th PTL is inferred to be equal to 0, which means 0-th PTL has no profile/tier/general constraints information.

Suggested solution as below: The value of pt_present_flag[ 0 ] is inferred to be equal to 01.

Typo 1: In the PPS syntax table, the text for( i = 0; brick_splitting_present_flag && i <= num_tiles_in_pic_minus1 + 1; i++ ) { should be replaced by for( i = 0; brick_splitting_present_flag && i <= num_tiles_in_pic_minus1; i++ ) {

Typo 2: In the semantic of bottom_right_brick_idx_delta[ i ], the "and and" should be replaced by a single "and"
