I have a client with a bit over 100 inbound links but Open Site Explorer shows total links on Subdomain as over 66,000, how can this be?

I have a client www.woodard247.com that shows only a bit over 100 inbound links. using the Open Site Explorer, they are a well trafficed local site and are not doing any grey hat or black hat techniques.  However the rankings for their main keywords have suffered recently and we cannot identify any duplicate content or keyword stuffing issues.  We have never purchased links or used link building software.  Now for the main question: When we run Open Site Explorer it shows only a bit over 100 inbound links on the page and the domain, but the subdomain shows over 66,000 total links!  How can this be possible?  Could this be a problem?  How can I find out what these links are since Open Site Explorer and Seo Spyglass both show only a hundred or so?

Can you show u a screenshot of the 66k links? I'm seeing Total Links of 845 for the root domain, from 15 Linking Root Domains on OSE right now.

I believe that is because it is showing internal linking as well.

Edit:
What I mean here is even though the domain is a subdomain, if you link from the main domain to the subdomain it appears as another domain is linking to you.
