Section 8.2 says:

 COMPRESSED ipv4_innermost_irregular {
    ENFORCE(is_innermost == 1);
    ip_id          =:=
      ip_id_enc_irreg(ip_id_behavior_innermost.UVALUE) [ 0, 16 ];
    ENFORCE(ip_inner_ecn == ip_ecn_flags.UVALUE);
  }

It should say:

COMPRESSED ipv4_innermost_irregular {
    ENFORCE(is_innermost == 1);
    ip_id          =:=
      ip_id_enc_irreg(ip_id_behavior_innermost.UVALUE) [ 0, 16 ];
    
  }

Notes:

I don't find any reason why IP-ID encoding in ipv4 irregular chain, should be dependent on ECN flags.
--VERIFIER NOTES--
"This errata is invalid. Those bits need to be bound in the format and needs to be done so in the irregular chain for the inner header which does special treatment for these."
