Polygon area creates negative values?

Hello,  I have a shapefile layer made up of many polygons. I am trying to calculate the acres of each polygon, which I have done many times. However my result is that some of the polygons are negative values, how does that happen? How can I get positive values? Or should I assume the absolute is still a correct value and just ignore the negative sign? I am using float and short integer.

 

Does it have to do with the integrity of the polygon layer?

 

Thanks!
