My FRQ file shows:

Pattern: Example:
-------- --------
^D+D++T 12300 SW 111TH S CANAL STREET RD

However, when I do Standardization Rules Analyzer on the ruleset,

it shows:

SS: 0000
UP: ^D+D++T
UD: 12300 SW 111TH S CANAL STREET RD
IP: ^D>D+TT
UO: User OverrideFlag

If this pattern is unhandled, should it be shown as unhandled in the
FRQ file?

The input pattern (IP) is indeed unhandled (UP) but there exists a user-defined override (UO) that specifies the bucketing for the pattern ^D+D++T (number, directional, unknown, directional, unknown, unknown, street type). The unhandled data (UD) have been handled by the override.
