Appendix B.2 says:

   6.  For i=1, 2, ..., c, do the following:

       A.  Set A2=H^r(D||I). (i.e., the r-th hash of D||1,
           H(H(H(... H(D||I))))

       B.  Concatenate copies of Ai to create a string B of length v
           bits (the final copy of Ai may be truncated to create B).

It should say:

   6.  For i=1, 2, ..., c, do the following:

       A.  Set A_i=H^r(D||I). (i.e., the r-th hash of D||I,
           H(H(H(... H(D||I))))

       B.  Concatenate copies of A_i to create a string B of length v
           bits (the final copy of A_i may be truncated to create B).

Notes:

Step 6A explains a number of rounds of hashing D concatenated with I, however the i.e. clause shows concatenating D with 1 in one place. Also, Step 6A has been changed from "A2" to "A_i", and Step 6B has been changed from "Ai" to "A_i".

[David Thompson sent additional corrections, which have been incorporated above.]
