Navigation only goes forward or backward 4 months

I'm relatively new to drupal and I'm having trouble with the calendar view. I've created a couple content types that utilize dates and I show these dates using a calendar view.

The problem is that when the calendar opens on the current month, I can only go back 4 months before it keeps rendering the last month. So if I'm on calendar/2011-11, the < Prev link says calendar/2011-10 but it renders as November 2011 even though the URL in the browser says calendar/2011-10.

Same thing happens when going forward. I thought it was because I didn't have events that far in the future or past, but even after I created some, it still does the same thing. In trying to troubleshoot this, I found additional issues when trying to display a full year or a single day.

I'm thinking this is some configuration issue with my view or perhaps the date limits (-3:+8) for the date fields in my content types but nothing has solved the problem. I couldn't find anything in searching drupal.org and I made a post that went unanswered for 3 weeks. Since I couldn't find any information I'm thinking it may be a bug related to my particular configuration (I am using multiday).

Can anyone please point me in the right direction or investigate this possible bug?

Thanks,
Dave
