Some Sakoku Law questions

[SolanSR]

I've been trying to get the Sakoku Law achievement for a few tries now. However I seem to be having some difficulties with the incidents. I'm fully aware that I need to get the isolationist result in 6 of these incidents and the answer seems straight forward: pick the isolationist answer whenever a related event shows up.

But now around 1760 with 7 out of 8 events passed and 5 isolationist results I seem to be stuck and unable to complete the achievement. Here's he incidents that are giving me issues;

Urbanization - Picked all the isolationist choices, yet got the neutral result. Thus did not get a tick for the achievement.

Proliferation of firearms - Picked all the isolationist choices here as well, got the open result. I got this event as 7th, after 1750.

Rising shogunate authority - Seems unable to fire. This one seems counter-intuitive as the requirements are all met except for the one where it asks 'is not a daimyo'. Seems a bit weird as I am a unified Japan and an administrative monarchy, so clearly not a daimyo. My guess is it is a poorly worded 'be the shogunate' instead.

So my main question here is: are there any things that influence these outcomes other then the decisions in the events? And if so, what are they so I can take that into account the next try I give this.

Thanks in advance for any help I get with this. It's been a right pain in my backside.

you must be did some mistakes... if you pick isolated all the time you must get isolate end allways (I never experinced opposite .I experinced incidents around 20 times in my 4-5 japan games and result was allways isolated if I picked isolated... so if results can end up diffrent its outside my experince

Yeah, I had issues getting it to. I’m not sure if it’s a bug or if it’s just worded poorly. @RedBstrd maybe you can shed some light on how to get this one?
