List of comment authors is lost during conversion XLSB to XLSM. Cells 8.5.1

Scenario: Aspose.Cells 8.5.1. I convert XLSB file to XLSM.

Issue: Comment author (Sam, Porter) is missing in the list of authors (see “\comments1.xml”), but new one is added (“user”).

After conversion:


Attached sample XLSB file: Comments.xlsb.

I tried another file (Sample_Comments.xlsb) with 3 authors: “ashloma” was removed and “user” was added.
