CSV import help

I’m having a problem getting CSV imports to assign a proper slug to players. I’m using the format:

#,First name,Last name
1000,kaleb,test

the output I’m getting is:

$opt_cat(ID): 5 Team slug: varsity

Team slug: varsity
Loading DataSource ...

Done.

First Name:

Last Name:

Title: No first or last name Slug:

$opt_cat(ID): 5

retval = 9382 ID: 1053 K: _mstw_tr_number V: 1000

retval = 9383 ID: 1053 K: _mstw_tr_first_name V: kaleb

retval = 9384 ID: 1053 K: _mstw_tr_last_name V: test

in the roster, I’m getting links like

http://example.org/players/no-first-or-last-name-93/?format=custom

instead of something like

http://example.org/players/kaleb-test/?format=custom

I’m not sure if this is intended or not, but I’m curious to know if there’s something I’m doing wrong
