JChem Excel auto-deletes sheets when opening new spreadsheet

I have a question about a potential bug in JChem for Excel that I was hoping you could help me with.  I’ve found that if I have a JChem_excel book open and I open a second Excel spreadsheet book file (either JChem or not), one of the sheets in the book that is opened is immediately deleted.  When I close this file it asks if I want to permanently discard the sheet marked for deletion from the book I opened, even though I haven’t actively deleted anything.  It’s a bit scary and I’ve almost lost some information this way a couple of times.  Is this something you recognize and is there something on my system that can be adjusted to avoid this?
