Return Statistics missing

When I run a rank performance with the stock formula -
(AvgRec- AvgRec8WkAgo)/ AvgRec
I don’t get return statistics on my universe - [

With the formula - (AvgRec- AvgRec4WkAgo)/ AvgRec - I get statistics.

Not a really an issue, but I thought I should report it.

It should be good now. Thanks for reporting it. The bucket affected had two stocks whose period returns were nearly identical on 2005-12-17 which caused a condition to arise due to floating-point error.
