asp.net core ef count rows containing a specific data

Question

I am trying to get data for a chart using 

 

var getData = await _context.WOMains.Where(s => s.OrgID == orgid).Select(s => s.WOType).ToListAsync();
            foreach (var item in getData)
            {
                WOMainChart = getData.Select(a => new WOChart
                {
                    ChartData = item,
                    ChartValue = item.Count()
                }).ToList();
            }

In the table I have three disting WOType, each added only one time, so 3 rows in total. However, when I run the query I get 22 as a count for each. What am I doing wrong?
