auto_filter doesn't work when there are rows before table header

[hypersonic64]

Hi,
I need a sheet with two rows followed by a table. This table has a header with filter.
This is what it should look like:

You can see the table header with filtering active in row 3.

But table filtering only works for me without the rows above the table.
As soon as I add the two rows using $writer->writeSheetRow() then the table header no longer shows filter option.
I'm using the 2023-06-02 release.

This is the code for the table only with correct set filter:
$writer = new XLSX_Writer();
$sheetName = 'TEST';
$rowFormat = ['height' => 20, 'font-size'=>10];
$formatList = ['col1'=>'string', 'col2'=>'string'];
$colOptions = ['auto_filter' => true, 'freeze_rows' => 1, 'suppress_row' => false];
$writer->writeSheetHeader($sheetName, $formatList, $colOptions);
$writer->writeSheetRow($sheetName, ['aaa', 'bbb'], $rowFormat);
$writer->writeSheetRow($sheetName, ['ccc', 'ddd'], $rowFormat);
$writer->writeToFile($file);

But when I try to insert the two rows above the table, then the filtering is no longer active in the table header.
As far as I know I need to write another header for inserting rows above a table, so my code looks like this:
$writer = new XLSX_Writer();
$colOptions = ['suppress_row' => true];
$writer->writeSheetHeader($sheetName, ['string'], $colOptions);
$writer->writeSheetRow($sheetName, ['HEAD'], ['height' => 30, 'font-size'=>20,'font-style'=>'bold']);
$writer->writeSheetRow($sheetName, ['SUBHEAD'], ['height' => 30, 'font-size'=>14,'font-style'=>'bold']);
$rowFormat = ['height' => 20, 'font-size'=>10];
$formatList = ['col1'=>'string', 'col2'=>'string'];
$colOptions = ['auto_filter' => true, 'freeze_rows' => 1, 'suppress_row' => false];
$writer->writeSheetHeader($sheetName, $formatList, $colOptions);
$writer->writeSheetRow($sheetName, ['aaa', 'bbb'], $rowFormat);
$writer->writeSheetRow($sheetName, ['ccc', 'ddd'], $rowFormat);
$writer->writeToFile($file);

The result is:

No filtering anymore.

Any hints?
Thanks
