Quicken is Double Counting Brokerage Account Funds

I use Quicken for Mac, and in my Brokerage account, it's showing all my investments (as downloaded from my brokerage firm), but is also showing an amount equal to their value as cash, resulting in it showing a balance double the actual value. I haven't been able to adjust or reconcile this, and it's become a real irritant! Any help would be appreciated!
