Getting duplicate items from external API after i applied paging

I have this formula inside my Power BI desktop to get data from external API using Pagination:-

let
   
    PageSize = 10000, // The number of rows you want to retrieve per page
    GetData = (Offset as number) =>
        let
            body=Text.Combine({"sAPIKey=",ApiKey}),
            SourceAPILogin=Json.Document(
                Web.Contents(
                    SmartAPI, 
                    [
                        RelativePath="apilogin",
                        Headers=[Accept="application/json", #"Content-Type"="application/x-www-form-urlencoded",#"API-Key"=Token],
                        Content=Text.ToBinary(body)
                    ]
                )
            ),
            tblGetUID = Table.FromList(SourceAPILogin, Splitter.SplitByNothing(), null, null, ExtraValues.Error),
            expGetUID = Table.ExpandRecordColumn(tblGetUID, "Column1", {"UID", "LanguageCode", "DatabaseVersion"}, {"Column1.UID", "Column1.LanguageCode", "Column1.DatabaseVersion"}),
            GetUID = expGetUID{0}[Column1.UID],
            Source=Json.Document(
                Web.Contents(
                    SmartAPI,
                    [
                        RelativePath = "jobs", // REST API endpoint
                        Query = [
                            Offset = Text.From(Offset),
                            Limit = Text.From(PageSize)
                        ], // Apply pagination
                        Headers = [Accept="application/json", #"Content-Type"="application/json",#"API-Key"=Token, UID=GetUID, DeviceID=ApiKey] // Headers
                    ]
                )
            ),
            // Convert the list to a table
            TableData = Table.FromList(Source, Splitter.SplitByNothing(), null, null, ExtraValues.Error),

            // Expand all records and lists in the table
            ExpandedData = if Table.HasColumns(TableData, {"Column1"}) then
                               Table.ExpandRecordColumn(TableData, "Column1", Record.FieldNames(TableData{0}[Column1]))
                           else
                               TableData // No need to expand if there is no "Column1"
        in
            ExpandedData,
    
    // Function to iterate over pages
    GetAllData = List.Generate(
        () => [Offset = 0, PageData = GetData(0)], 
        each Table.RowCount([PageData]) > 0, 
        each [Offset = [Offset] + PageSize, PageData = GetData([Offset])], 
        each [PageData]
    ),

    // Combine all the paged results into a single table
    CombinedData = Table.Combine(GetAllData),
    #"Sorted Rows" = Table.Sort(CombinedData,{{"JobCode", Order.Ascending}})
    
in
    #"Sorted Rows"

 but the problem i am facing is that i am getting the same item twice, as follow:-

so what could be the reason?Thanks
