Why am I getting an error message when using Wildcard for file based lookup?

[sylim_splunk]

I'm trying to use WILDCARD for file based lookup and get an error message, "match_type is malformed" as below - According to the descriptions in UI page, I'm using WILDCARD(A*, B*,..) and get the error.

Optionally set up non-exact matching of a comma-and-space-delimited field list. Format is (, ,...). Available values for match_type are WILDCARD and CIDR.

This is a UI bug and will be corrected.
Correct way for match_type for multiple fields is like, WILDCARD(A*), WILDCARD(B*) as described in spec.

match_type =
A comma and space-delimited list of < match_type >(< field_name >)
specification to allow for non-exact matching
The available match_type values are WILDCARD, CIDR, and EXACT. EXACT is
the default and does not need to be specified. Only fields that should
use WILDCARD or CIDR matching should be specified in this list
