Hi Milan,We suspect that the reported problems are might be due to the
contents in the input word document which used at your end. We need to investigate with the contents in your input Word document
to reproduce the exact problem at our end. So, could
you please provide us the input Word document which used at your end. Thereby, we will
analyze further and provide you the appropriate solution at the earliest. Note: If you
have any confidential data in your Word document, please replace with some
dummy data and provide us the same. We just need your
document to recreate the problem you face.Regards,Suriya M.

The problem occured after I tried to create a table in the footer and add initials and a page number. The version that i used is `"@syncfusion/ej2-react-documenteditor": "20.1.48".`
