Search results not displaying properly

When I do a multisite search, the results it gives me look like this:

Search results

...

- comments

...

- comments

...

When I do a regular (non-multisite) search, I get the correct results.

So, let's say I search for "win" on multisite.example.com. In a regular search, I get 3 results, and it shows them to me formatted properly. When I search for "substantially" on multisite.example.com/site1, I get 4 results, and it shows them to me formatted properly.
However, when I search for "win" or "substantially", using the multisite search on either of the sites, all I get is this "... - comments". It does, however, give me the correct number of results.

Has anyone else run into this problem? Is this a problem with my setup, somewhere, or is there a problem with the module??

I've tried changing my theme back to Garland, in case it was an issue somewhere with the html.

Here is my setup:

Multisite Configuration
Site id Table prefix Site URL Operations
4 www_ http://multisite.example.com delete
5 site1_ http://multisite.example.com/site1 delete
6 site2_ http://multisite.example.com/site2 delete

In my codebase:
sites/default
sites/multisite.example.com.site1
sites/multisite.example.com.site2

In my Database:
www_sessions ( with $db_prefix = array('default' => 'www_',)
site1_sessions
site2_sessions

Thanks for the module!
