List.Transform Error when using List.Contains or List.ContainsAny but not when using OR comparison.

The  ..  notation only works with integers or with single characters. For example {"A".."Z"}  works but {"AA".."ZZ"} doesn't.

Create a numeric list {2020..2030}  and then use Text.From(_)

= List.Generate(()=> 2020, each _ < 2031 , each _ +1, each Text.From(_))

or

= List.Transform({2020..2030},each Text.From(_))
