Wrong Data In Query

I am not sure how this query I made is pulling up wrong data. Everything else is fine, except for 1 row of data. It is supposed to pull how many demonstations were scheduled for that day and how many were executed. It comes up with 4 demos and 8 executed. That can't be right. I checked it with the actual data and there are 6 demos total and 4 executed. Anyone know what could be going on there? For the other 30 something records it works just fine.

SQL:
SELECT [Promo count].PromoNo, [Promo count].[# of Demos], Count(DemoOrder.Status) AS CountOfStatus, CountOfStatus/[# of Demos] AS Percentage
FROM [Promo count] INNER JOIN DemoOrder ON [Promo count].PromoNo = DemoOrder.PromoNo
WHERE (((DemoOrder.Status)="E"))
GROUP BY [Promo count].PromoNo, [Promo count].[# of Demos];
