Imams Causing Heretics?

[Byg]

There are 16 Imams in this settlement and heretics are appearing. It is 84% Islam when one would expect 100% as it has always been Islam since turn 1. Anyone know what file needs to be edited to reverse this?

The 16% are a result of the minimum 4 heretics in that region. Check out descr_campaign_db:

The thing is that those heretics have only just started appearing (I think). Now heretics only start to appear when religion is low (at least that is my long standing observation of their appearance in my own lands), so my concern is over why religion is low there in the first place as that region has more clerics than any place I have ever seen since I have been playing this game.

I have not recently changed any of the code below:

<max_witches uint="15"/>
<max_heretics_per_region uint="1"/>
<max_heretics uint="30"/>
<max_heretics_conversion_modifier float="1.0"/>
<max_inquisitors_per_region uint="1"/>
<max_inquisitors uint="12"/>
<heretic_conversion_rate_modifier float="0.0075"/>
<heretic_conversion_rate_offset float="0.025"/>
<witch_conversion_rate_modifier float="0.0"/>
<witch_conversion_rate_offset float="0.02"/>
<inquisitor_conversion_rate_modifier float="0.010"/>

I guess that settlement is producing imams that do not leave the settlement. They only leave when they become heretics, but they're still immovable as heretics so they stay... that's what it looks like
