I suspect you have not configured cflowd to store AS information.  In
the cflowd.conf file, for each router you gather stats from there is a
line used to specify what stats to gather.  See below.

#      COLLECT - What to save from the flow-export data received by
the
#         Cisco.  The possible collect options:
#
#           protocol - IP protocol table (pkts/bytes per protocol...
#             ICMP, UDP, TCP, IGMP, etc.)
#
#           portmatrix - port matrix.  Pkts/bytes from port A to port
B.
#
#           ifmatrix - interface matrix.  Pkts/bytes from interface A
#                      to interface B.
#
#           nexthop  - nexthop table.  Pkts/bytes to each IP next hop.
#
#           netmatrix - network matrix.  pkts/bytes from 
#                       network A to network B.
#
#           asmatrix - AS matrix.  pkts/bytes from AS A to AS B.
#
#           flows - raw flow data.
#

For example:

################
# TIMBUCKTOO 9 #
################

CISCOEXPORTER {
        HOST:           123.45.6.7
        ADDRESSES:      { }
        CFDATAPORT:     2055    # Port on which to listen for data.
        LOCALAS:        42    #  Local AS of Cisco sending data.
        COLLECT:        { asmatrix, netmatrix }
}
