Data Loss Between Source and Query
I am having an issue similar to this post.
My source is a folder with several Excel files. I am combining the data from all of the Excel files. when I do so everything populates as expected except for one single cell. It dispalys as null. It is a data colum in which other dates populate correctly. I have tried to change the date of the source cell and I get the same results. With multiple Power BI files, I have tried refreshing, reimporting, and even the Advance Editor trick mentioned in the above post but nothing has solved the issue.
Any assistance would be greatly apprecaited.

1. Try to add any simple step to that query in PowerQuery editor. For instance, rearrange two columns or any other simple step. And hit apply.
2. If item #1 will not help then post code of this query here (in readable view, please :))

Did I answer your question? Mark my post as a solution!I have tried adding a step and it did not result in the cell in question to populate.
Please see below for the code:
let
Source = Folder.Files("FOLDER_LOCATION"),
#"Filtered Hidden Files1" = Table.SelectRows(Source, each [Attributes]?[Hidden]? <> true),
#"Invoke Custom Function1" = Table.AddColumn(#"Filtered Hidden Files1", "Transform File from Candidate Tracking Log", each #"Transform File from Candidate Tracking Log"([Content])),
#"Renamed Columns1" = Table.RenameColumns(#"Invoke Custom Function1", {"Name", "Source.Name"}),
#"Removed Other Columns1" = Table.SelectColumns(#"Renamed Columns1", {"Source.Name", "Transform File from Candidate Tracking Log"}),
#"Expanded Table Column1" = Table.ExpandTableColumn(#"Removed Other Columns1", "Transform File from Candidate Tracking Log", Table.ColumnNames(#"Transform File from Candidate Tracking Log"(#"Sample File"))),
#"Removed Columns" = Table.RemoveColumns(#"Expanded Table Column1",{"Source.Name"}),
#"Promoted Headers" = Table.PromoteHeaders(#"Removed Columns", [PromoteAllScalars=true]),
#"Sorted Rows" = Table.Sort(#"Promoted Headers",{{"Candidate Name", Order.Descending}}),
#"Filtered Rows" = Table.SelectRows(#"Sorted Rows", each ([Candidate Name] = "Test 1" or [Candidate Name] = "Test 2")),
#"Sorted Rows1" = Table.Sort(#"Filtered Rows",{{"Candidate Name", Order.Ascending}, {"DO NOT EDIT", Order.Ascending}})
in
#"Sorted Rows1"
