grand total in table visual is not summing values correctly

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

how can i use (Has one filter) funuction if i have multiple coulmns in my table?

Hi,

The root cause for this behavior is that typical dax functions don't do "visual level calculations" and instead the calculation is done on filter context. In practice this means e.g. this:

Data:

Measure:

Measure 4 = AVERAGE('Table (9)'[Value])

Now, one could think that this will result in Average of 20 since (10+30)/2 = 20. However here is the end result:

 

So (10 + 10 + 30) / 3 = 16,67


Measure resulting in expected end result could be e.g. this:

Measure 5 =

AVERAGEX(

SUMMARIZE('Table (9)','Table (9)'[Dimension],"Average",AVERAGE('Table (9)'[Value])),[Average])

This measure first creates aggregate table and then takes average of that table resulting in the expected 20.

In your example you can use SUMX instead of AVERAGEX. So first create calculated table within your measure. Ypu can consider placing it into variable like this:

Measure 5 =

var _vtable= SUMMARIZE('Table (9)','Table (9)'[Dimension],"Average",AVERAGE('Table (9)'[Value])) return

AVERAGEX(_vtable,[Average])

In your case replace the calculated column and expression matching your table and then use SUMX.
