Custom function extrapolating the import

[dataanalyst88]

Hi All, 

I have a simple function that is used to check if a value exists in a different table or not. Before invoking this function2 I do use function to get the path, and then pick the highest parent from there and then use the highest parent value in function 2. 

function 1 : 

I use the get path function shared by @Scott_Parker 

DAX's PATH function equivalent Custom Column in Po... - Microsoft Fabric Community

function 2

let
Source = (name as text) =>

let
Buffered = Table.Buffer(Table.SelectColumns(DV_Columns,{"NAME", "COLUMN_NAME"})),
CheckTable = List.Contains(Table.Column(Buffered,"NAME"),name)
in
CheckTable

in
Source

When trying to do this I get infinite number of rows when importing the data. But when I use count rows on Power Query it is giving me the correct number of rows. Not sure where I am going wrong. 😞
