Item count is 395, but should be 393? I don't understand. Where're the extra pieces came from? Please comment. Thanks.

Hello Fong,

Somehow the count of the number of items assigned to a particular category in Inventory became incorrect. If you press the Rebuild button, the count will be adjusted to reflect the actual number of items assigned to that category.

Without knowing exactly what you have done between the last integrity check that did not have these errors, and the current integrity check, it is impossible to know what might have caused these errors.

This count is only used to make sure you don't delete a category being used by an item. There's no other risk associated with correcting the count.
