Data required for Geocoding (Alchemy)

I created a custom .gbfs file using Alchemy / IMPORT STREETS (see .Alchemy script below). There were no errors nor warnings during the Alchemy processing.

When I load the file into GBFS Tool, I get
Valid:Yes
Info:
Data Format v2.7
Supports: mapping, reversegeocoding, routing

Sure enough, I can use the file for these three things, but when I try Geocoding I get an exception:
"None of the installed datasets support geocoding for USA"

Any tips on what might be causing this problem would be very much appreciated.

Thanks in advance,

Tim.

Here's my .Alchemy script to create zroad1.gbfs:

OUTPUT zroad1;
DATASET "xxxxxx" ;
COPYRIGHT "yyyyyy" ;
COUNTRY "USA";
REGIONS ["USA", "MountainWest"];

? "Press <enter> to continue this import";
readLine();

IMPORT STREETS [
ID = int(%ROAD_ID),
BASENAME = %STNAM2,
L_REGION 1 = %L_CITY,
LNREFADDR = string(%LHI),
LPOSTCODE = string(%L_ZIP),
LREFADDR = string(%LLO),
NAME = %FULL_NAME,
NM_PREF = %DIR,
NM_SUFF = %SFX,
R_REGION 1 = %R_CITY,
RNREFADDR = string(%RHI),
RPOSTCODE = string(%R_ZIP),
RREFADDR = string(%RLO),
TYP_AFT = %TYP,
TYP_BEF = %PRETYPE
] FROM "road";
