Mismatch error during delta sharing sourced table

Hi, 

We are using databricks and within it the delta sharing connector, for some reason we are receiving errors when we are querying two tables, this is one of the tables query in advanced editor and I don't understand why we get the error message. 

let
Source = dim_delay_category,
  #"Detected Type Mismatches" = let
    tableWithOnlyPrimitiveTypes = Table.SelectColumns(Source, Table.ColumnsOfType(Source, {type nullable number, type nullable text, type nullable logical, type nullable date, type nullable datetime, type nullable datetimezone, type nullable time, type nullable duration})),
    recordTypeFields = Type.RecordFields(Type.TableRow(Value.Type(tableWithOnlyPrimitiveTypes))),
    fieldNames = Record.FieldNames(recordTypeFields),
    fieldTypes = List.Transform(Record.ToList(recordTypeFields), each [Type]),
    pairs = List.Transform(List.Positions(fieldNames), (i) => {fieldNames{i}, (v) => if v = null or Value.Is(v, fieldTypes{i}) then v else error [Message = "The type of the value does not match the type of the column.", Detail = v], fieldTypes{i}})
in
    Table.TransformColumns(Source, pairs),
  #"Added Index" = Table.AddIndexColumn(#"Detected Type Mismatches", "Row Number" ,1),
  #"Kept Errors" = Table.SelectRowsWithErrors(#"Added Index", {"borders", "delay_category_name", "delay_category_id"}),
  #"Reordered Columns" = Table.ReorderColumns(#"Kept Errors", {"Row Number", "borders", "delay_category_name", "delay_category_id"})
in
  #"Reordered Columns"

The source table's datatypes are: 
border --> DOUBLE
delay_category_name --> STRING
delay_category_id --> INT
