Verify if the row selector is hidden
Verify your Chart configuration 
settings > have Display Row Selector turned on. The row selector may be hidden and only show selected values.
Check if your columns are hidden
In Result manipulation 
> Columns, ensure that all columns are visible.
Look into your metric filter
In Result manipulation > verify your Metric filter, perhaps you hid part of the result. For example, in this image, the number in the left should be 0 instead of 20.
Verify that you are not hiding part of the result
In Result manipulation > Hide part of the result, ensure you are not hiding data > Apply.
Check that no filter is applied
At the top of the page and on the left side, ensure that you did not add a filter on your data.
Verify the Top/Bottom filter
In Result manipulation > Check the Top/bottom filter > Untick Top and Bottom > Apply.
Compare with actual data
Finally, if you still see missing values, verify your sources of data. For example, open sample tickets and compare the results with your report.
