How to show the sum instead of the mean in total line of a table of a quick measure field

[FelipeGomara]

Hey guys, its fairly a simple question regarding PowerBI Desktop:

I've created a new measure with "quick measure" (named as "Qtd. Integralizada", it is a division of two sums) and inserted it on a visualization table on my project.

The problem is, instead of showing the total sum on the last line of the table, it is showing the mean, as highlighted in yellow below:

Normally, I would change this by right clicking the field on the visualization editing and selecting "Sum" as depicted below:

But instead, this options are not available when right clicking the newly created field:

Does anyone know how can I work around this issue?

@FelipeGomara , If we create a measure that uses row context. grand total might not match

Using the column in visual have a new measure like

Sumx(summarize(Fact, Fact[Codigo IF], Fact[ISIN], Fact[Subori], "_1", [QTD measure]), [_1])

I don't know if my knowledge on Power BI is too scarce, but I did not understand this solution, is there a topic that I ought study in order to conceive this explanation?
