Presence of “, BC” in input string affects standardization choices by the Geocoder

NOTE: this is an isolated case.

In the address below, when the address is provided with “, BC” at the end, the Geocoder standardizes to an address that is different than when “, BC” is removed.

addressString: 201 36 W 1, NORTH VANCOUVER, BC
Geocodes to: UNIT 201 -- 36W Trans-Canada Hwy, West Vancouver, BC
Score: 90
Faults: [UNIT_DESIGNATOR.missing:0, UNIT_NUMBER.notMatched:1, LOCALITY.isAlias:1, STREET_NAME.isHighwayAlias:0, STREET_DIRECTION.notMatchedInHighway:0, STREET_TYPE.missing:6, STREET_TYPE.notSuffix:0, CIVIC_NUMBER_SUFFIX.notMatched:1, MAX_RESULTS.too_low_to_include_all_best_matches:0]

addressString: 201 36 W 1, NORTH VANCOUVER
Geocodes to: UNIT 201 -- 36 W 1st Ave, Vancouver, BC
Score: 88
Faults: [LOCALITY_GARBAGE.notAllowed:3, UNIT_DESIGNATOR.missing:0, UNIT_NUMBER.notMatched:1, STREET_TYPE.missing:6, PROVINCE.missing:1]

This case is even more interesting - with the "BC" on the end, there are actually 5 different results with a score of 90.
One of them is "UNIT 201 -- 36W W Pender St, Vancouver, BC" which gets a "Street_Name.PartialMatch" penalty for the "1" to be a partial match of "pender"? AND the "W" gets a civic number suffix notMatched - (as in 36W) but why isn't the W just consumed by the "w" in "W pender"? Something funny is going on there.

Actually it seems like what is happening is that the "W" is being echoed as a civic number suffix (even though it should have been interpreted as the street directional, and this is affecting the scoring. If I set echo=false I get different results. I don't believe echo should be effecting the scoring. It also shouldn't be echoing things that are interpreted in other ways.

Actually nevermind, all that can be explained - the "north" in north vancouver is being used as the directional for the "west pender", it is getting a Street_Direction.notMatchedInHighway fault. Meanwhile the 1 is a partial match for highway "1A" which apparently is an alias for west pender.
