@Arthurvdv can you have a look?

Maybe enable the SplitButton feature for the export buttons?

area(Promoted)
{
    group(Category_Process)
    {
        Caption = 'Process';

        group(Export)
        {
            ShowAs = SplitButton;
            actionref(ExportNow_Promoted; ExportNow) { }
            actionref(Schedule_Promoted; Schedule) { }
        }
        actionref(StopExport_Promoted; StopExport) { }
        actionref(ClearDeletedRecordsList_Promoted; ClearDeletedRecordsList) { }
        actionref(DeleteOldRuns_Promoted; DeleteOldRuns) { }
    }
}
