Power Query -Delete column substring corresponding to the text of another column (insensitive case)

informer 

You merely need to modify the Table.ReplaceValue function I provided you in your previous similar question:

    #"Remove Acronyme" = Table.ReplaceValue(
        #"Previous Step",
        each [Acronyme],
        null,
        (x,y,z) as text => let 
                        pos = Text.PositionOf(x,y,Occurrence.All,Comparer.OrdinalIgnoreCase)
                    in 
                        List.Accumulate(
                            List.Reverse(pos),
                            x,
                            (s,c)=> Text.RemoveRange(s,c,Text.Length(y))
                        ),
        {"Nom","Volume","Circulating Supply"})

#"Previous Step"

#"Remove Acronyme"

Note that in the first row of the first column, it is removing both instances of the Acronyme. Depending on exactly what you want to do in that instance, you may need to change the logic a bit.
