list.intersect not working case?

Hello,

I need to make List.Intersect but found case I am not able to resolve. I tried to simplify to maximum my issue.

I have two tables.

- One named TPR contains two fields : a identified of issue, a list - here simplified to one - of tags, field named TOP here

- A second table named TFLT that contains several Filters, per row I have a list of tags separated by a comma

What I need to get is to find the intersection between { [TOP] } in Table TPR and { [TOPL] } in table TFLT

In table TPR, I have one row where my List.Intersect function gives expected result and another row where this is not working. And I cannot figure out what is wrong. I removed any blank, '_'... to put aside basic issues but still this is not working...

TPR table

TFLT table

where Filter0 is List.Count(List.Intersect({Text.Split([TOP]," "),Text.Split(TFLT[TOPL]{0},",")}))>0

and Filter1 is List.Count(List.Intersect({Text.Split([TOP]," "),Text.Split(TFLT[TOPL]{1},",")}))>0

let
    Source = Table.FromRows(Json.Document(Binary.Decompress(Binary.FromText("i45WCjBU0lEKcVKK1QGyjUBs/wBDU3cjA8cQFxdDA98Ap5z85OzUopg8pdhYAA==", BinaryEncoding.Base64), Compression.Deflate)), let _t = ((type nullable text) meta [Serialized.Text = true]) in type table [PR = _t, TOP = _t]),
    #"Changed Type" = Table.TransformColumnTypes(Source,{{"PR", type text}, {"TOP", type text}}),
    #"Added Custom3" = Table.AddColumn(#"Changed Type", "Filter1", each List.Count(List.Intersect({Text.Split([TOP],","),Text.Split(TFLT[TOPL]{1},",")}))>0),
    #"Added Custom4" = Table.AddColumn(#"Added Custom3", "Filter0", each List.Count(List.Intersect({Text.Split([TOP]," "),Text.Split(TFLT[TOPL]{0},",")}))>0)
in
    #"Added Custom4"

Thanks in advance for your help!
