Argument out of range exception in DUCE library

[Jaroslaw Kuchta]

I wrote a simple WPF application with SfSpreadsheet control and open various XLS/XLSX workbooks. From time to time I have a runtime "Argument out of range" exception which occurs in DUCE library. It looks like something tries to remove something not existent. I can't reproduce this error as it occurs rarely. Please help.
