Electronic MPG gauge-issue

Hey guys,
2000 Navi with the overhead console digital MPG gauge that tells the average MPG. I am having an issue with mine now. It is not calculating the average anywhere close to what I am actually getting. I reset it by pressing both buttons and it went to zero, but even after several miles, it still says my average is really low.
It used to work fine, i could reset it, and while i was easy on the gas, the average could bounce up to say 24 mpg, then would drop with the more gas i gave it. it would then average out after about 50 miles or so to the normal 14-15mpg or so in town

NOW: when i reset it, and while driving very easy or idling at a red light, the average will barely fluctuate to 6 mpg. it is not fluctuating like it used to.
my MPG is fine, i calculated and i get what i have always got, around 14-15 mpg in town and 17 on highway. just the digital one in the console is acting up.
i did pull the negative off the battery to try and reset it, but no luck. please help

Any chance you switched the display over to metric or have it on real time MPG instead of average MPG?
