Unable to override default summarization when column title is similar to data categorisation labels

[jpretorius]

Issue:
When a column title includes the name of a Data Category label (Address, City, Continent, Place etc.) the default summarization used on the field becomes an average and there is no way to override the behaviour.

Steps to reproduce:

1. Create a new blank table in query editor
2. Use column headers that include the labels used under the Data Category menu in Power BI
3. Feel free to add a prefix of suffix onto the labels, for example: [Number Placed], [Addressees], [Placements], [Continental Appointments]
4. Set the data type to whole number for each column
5. Import the query
6. Drag the fields into a table visual and note that the default summarization used in the visual is an average
7. Under the Modelling menu, the default summarization is set to Sum but this appears to be overridden by some internal logic within Power BI

Sample m query below:

let
    Source = Table.FromRows(
		Json.Document(Binary.Decompress(Binary.FromText(
			"i45WMlTSUTI2ARIWQGxuphSrE61kBGSaQoUswCIgBWZAbAkSsQQLgRSYA7EBWDg2FgA="
				, BinaryEncoding.Base64), Compression.Deflate
			)
		)
		, let _t = ((Int64.Type) meta [Serialized.Text = true]) 
			in type table [
				Placements = _t
				, #"Number Placed" = _t
				, #"Continental Appointments" = _t
				, Addressees = _t
				]
	)
in
    Source

Expected Behaviour
The default summarization behaviour set on a field (under the Modelling header) should override any 'internal' default summarization applied by Power BI.

Hi @jpretorius,

I got information internally that it is a known issue, by design for now. But there is no ETA currently.
