100% Wt on a factor: Factor Rank different form System Rank

Working on a new ranking system I placed 100% of the Weight onto a single factor and looked at the ranks and composite ranks.
The prior weighting scheme kept showing up for about 8 times that I looked at rank, as other factors had numbers in the columns before zeroing out the column weights and showing the Composite rank equal to the factor rank.

Why did that happen and how do I avoid it in the future?

IT APPEARS TO BE A CACHING ISSUE WITH SAFARI. REFRESHING THE SCREEN IN THE SETTINGS PAGE PRIOR TO PROCESSING RANKS ELIMINATES THE ISSUE.
