[amibroker] Drawdown (Again)

I know this is a delicate area, but 
it's important so I'll wade in. I have read the help file 
(carefully).
Attached is a file (noname.jpg) 
showing Fred's equity plot for this single stock backtest. It shows a Max DD of 
31%, from a positionsize fixed at $10,000. The equity never goes below 
$7200.
Also shown is a section of 
the AB report. Here the 'max system DD' is shown as $5121, but the 'max 
system % DD' is -128%.
 
How can we have a 'max system % DD' 
greater than 100% (and remember Max DDs are measured peak to trough, not 
relative to initial equity)?
 
Any clarification will be most 
welcome!
 
Steve
