Crosstab 12 Months Doubling Up On A Month

Have a crosstab query for a running 12 months that is used for a report and I noticed today that each month is correct except that it is also picking up Feb of last year as well as this year. All other months are good. No other pre-queries have any date ranges in them. Anyone know what I have to do to prevent this problem? Below is my SQL.:confused:

TRANSFORM Sum([92660ScorecardUnionName].Hrs) AS SumOfHrs
SELECT [92660ScorecardUnionName].EMPID, [92660ScorecardUnionName].Category, [92660ScorecardUnionName].OPID, [92660ScorecardUnionName].NAME, [92660ScorecardUnionName].Description, Avg([92660ScorecardUnionName].Hrs) AS [Avg Of Hrs]
FROM 92660ScorecardUnionName
GROUP BY [92660ScorecardUnionName].EMPID, [92660ScorecardUnionName].Category, [92660ScorecardUnionName].OPID, [92660ScorecardUnionName].NAME, [92660ScorecardUnionName].Description
PIVOT Format([Date],"mmm") In ('Jan','Feb','Mar','Apr','May','Jun','Jul','Aug',' Sep','Oct','Nov','Dec');
