Word 2010: Number alignment wrong at 10

Default number alignment has incorrect spacing after you reach 10.

The solution is to right click a paragraph and select Adjust List Incidents, then increase the text indent until you're satisfied. 

But be aware that when reaching 100 or 1000 the list could be in peril again.
