Wrong Total line table

twister8889 Just change your measure to this:

Value = 
  IF(
    HASONEVALUE([Product]),
    sum([Values]),
    SUMX(SUMMARIZE('Table',[Product],[Category],[Type],[Month],"Sum",SUM([Values]),[Sum])
  )

Sorry, posted the wrong thing earlier, I edited it.

This looks like a measure totals problem. Very common. See my post about it here: https://community.powerbi.com/t5/DAX-Commands-and-Tips/Dealing-with-Measure-Totals/td-p/63376
