Cells.deleteColumn in table 21.2 vs 21.3 version

Have the following code that was working in 21.2 Java Aspose.Cells version:

The simply iterates over all worksheets. If there is a table on the worksheet (ListObject), it simply deletes the column at index 1. It is attentionally using the Cells.delete column API.
This was working on 21.2 version. Once we upgraded to 21.3 version, the Cells.deleteColumn link throws and exception:
Cannot read field “c” because “” is null

Attached is the Excel file.

for (Object obj : workbook.getWorksheets()) {        
	Worksheet worksheet = as(Worksheet.class, obj);
	ListObjectCollection tables = worksheet.getListObjects();
	for (int i=0;i<tables.getCount();i++){            
		Cells cells = worksheet.getCells();
		cells.deleteColumn(1); // exception here in 21.3 version.
