Comment 6 for bug 1622757

Charles, look at the image I posted. It is the custom columns tab on bulk metadata edit dialogue not the book list. And I am referring to the right click (context) menu items Step Up and Step Down in numeric text boxes not the spinners.

I am attaching another image to this post, which shows the after effects of doing a Step Up in Bulk Metadata Edit - existing values overwritten by -999999 rather than being incremented by 1.
