Addition Ctls stream in XLS file after upgrade Cell .Net 21.1

Hi there,
Can you tell me why there is an empty stream called Ctls in the output file when loading XLS file and save back? This behavior is only seen after upgrading Aspose Cells .Net to version 21.1. Is it expected? And are there any options to do not produce that stream when saving?
Thanks.
