Section 11.4 says:

It should say:

163 30  159:  SEQUENCE {
166 06    7:   OBJECT IDENTIFIER
           :    id-GostR3410-2001-CryptoPro-A-ParamSet
175 30  147:   SEQUENCE {
178 02   33:    INTEGER
           :     00 FF FF FF FF FF FF FF FF FF FF FF FF FF FF FF
           :     FF FF FF FF FF FF FF FF FF FF FF FF FF FF FF FD
           :     94
213 02    2:    INTEGER A6
217 02   33:    INTEGER
           :     00 FF FF FF FF FF FF FF FF FF FF FF FF FF FF FF
           :     FF FF FF FF FF FF FF FF FF FF FF FF FF FF FF FD
           :     97
...

Notes:

EC parameter 'b' is incorrectly specified using its base10 value where base16 expected.
--VERIFIER NOTES--
From Jim Schaad:
Short integers are dumped by the tool using base 10 not base 16. This was auto generated from the tool.

The difference in the format easy to see from the single line to the multiple line for base16 dumps.

(At best it is editorial in terms of clarification between bases)
