genetic builder b130 - Automatic filters appear to not work for island #1as an init pop filter

Turning on a couple of autofilters in the ranking tab: no trades and too few trades, (when there are no init pop filters in the gen tab selected) slows down the speed at which all islands fill up except island #1. This tells me two things, first thing auto-filters are applied as init pop filters for most islands. Second thing island #1 is not effected by auto-filters.  Island #1 pool can be viewed and I can confirm my second point.

I'm not talking about strats per hour here I'm talking about looking at how full each island is after x minutes. Try it with too-few/no-trade autofilters on/off. off= all islands fill quickly and evenly. on= islands fill up more unevenly and slower except island #1 which always fills first. Incidentally, with those auto-filters turned on the strats per hour actually goes way up even though the islands are filling slower. I think this phenomena occurs only if init pop filters is empty in the genetic build tab.

I'll attach my build in case you need help reproducing.

I have an additional question, does the autofilters also apply to following generations or just init pop?
