Missionaries have +2 extra spread and I don't know why

[ImperatorSalad]

So missionaries have a base of 3 spread charges, right? Well in this latest game I'm playing I notice they have 5. I'm not playing India, I don't have Hagia Sophia (or any wonders), I don't have the Mosque (or any worship buildings, in fact I haven't even selected a worship belief yet), and I don't see anything else that would be causing this. I'm have all the DLC and expansions enabled, I'm playing as Jadwiga on Immortal Difficulty, my pantheon is God of Craftsmen, my beliefs (so far) are Reliquaries and Holy Order, and I'm Suzerain of Kandy, Yerevan and Venice. I have Barbarian Clans, Heroes & Legends, Monopolies & Corporations and Secret Societies enabled, and I'm a member of the Voidsingers. My government is Autocracy and my policies are Urban Planning, Charismatic Leader, Caravansaries and Scripture.

The mods I have enabled are as follows:

Immersive Dialogue
Gedemo's Caesar
Gedemo's Goa City-State
Gedemo's Honolulu City-State
Gedemo's Kition City-State
Gedemo's Knossos City-State

Sukritact's Global Relations Panel

I don't see what could be causing this. My guess is that one of these mods is either doing something it shouldn't or has some feature I'm unaware of. That or there's some completely obvious reason that I missed. But if anyone could maybe shed some light on this, that would be greatly appreciated.

What about your dedication? There is a golden age dedication that gives missionaries +2 spreads, and you are in a golden age.

I'm a dumb-dumb. Every place I looked when I googled what gives missionaries extra spreads failed to mention this. Thank you!
