Top or Active?

Okay so heated discussion in our flat about this. Not the difference (if there is one) but how gaydar describe your ‘role’ in life.
So Matt insisted it was Active and I thought it said top. Turns out we were both right. For some reason known only to gaydar, the PC shows Matt as Active and me as Active/Versatile (slut). My Mac on the other hand shows Matt as Top and me as Top/Versatile.

So if anyone from gaydar is reading this can you explain please. Confused of Balham.
