install PeaZip 6.0.0 & Sumatra PDF3.1.1 both with context menu integration.
Then open the context menu of a pdf file (where both application have added a context menu entry).
Sumatra pdf placed its "Print" entry directly above Peazips "add to zip".
When you select the "add to zip"-entry we will get an off-by-one and the "print"-entry of Sumatra-PDF will get invoked erroneously. All entries below this one are off-by-one too.
