Differences between excel and power query sorting results

[Wishmaster89]

Hi All

I've been playing around with sorting in excel and power query. Power query gives me the result i expect and excel doesn't and i can't figure out why.

Sample data

status to check for QAR comparison 18-09.xlsx
	A	B	C	D	E	F	G
1	ULN	Completion_Status	Learning_Outcome	Standard_Description	Learning_Start_Date	Learning_Planned_End_Date	Learning_Actual_End_Date
2	1	1	9	Credit Controller / Collector	16/08/2017 00:00	15/02/2019 00:00
3	1	2	1	Credit Controller / Collector	16/08/2017 00:00	15/02/2019 00:00
4	1	2	1	Credit Controller / Collector	16/08/2017 00:00	15/02/2019 00:00	20/06/2019 00:00
test_v4

M query for the sort

let
    Source = Excel.CurrentWorkbook(){[Name="test_v4"]}[Content],
    #"Changed Type" = Table.TransformColumnTypes(Source,{{"ULN", Int64.Type}, {"Completion_Status", Int64.Type}, {"Learning_Outcome", Int64.Type}, {"Standard_Description", type text}, {"Learning_Start_Date", type datetime}, {"Learning_Planned_End_Date", type datetime}, {"Learning_Actual_End_Date", type datetime}}),
    #"Sorted Rows" = Table.Sort(#"Changed Type",{{"Learning_Start_Date", Order.Ascending}, {"Learning_Planned_End_Date", Order.Ascending}, {"Learning_Actual_End_Date", Order.Ascending}})
in
    #"Sorted Rows"

Now with the same data in the excel sheet, if i replicate the sort in excel like in the attached image the data comes out like this(Column G value changes row). Any one able to tell me why please?
