Hello ZC Gurus,
In the bottom left corner of my Admin Home page, the number of Pending Orders shown is not correct. For example, the number currently shown is 9. However, when I click on "Pending:", it correctly shows me that I have in fact only 2 pending orders. Note: When I had only 1 pending order the Admin Home page was reporting 8, i.e. it is currently adding 7 to the real value.

Background Info:
New site; v1.3.8; never been upgraded; no addons installed.
This problem became apparent after I deleted about 40 test orders. It may have been there for a while.

Obviously I've customised my site to suit my business needs and as a newbie could have done something wrong.
Any input much appreciated.
