Multistore - how to enable different countries for different domains

[mysho]

I am trying to setup a multistore with 4 domains: .EU / .DE / .CZ / .SK

I would like to have active countries (for shipping) on each domain like this:

.EU: all EU countries 
.DE: Germany + Austria
.CZ: Czech republic
.SK: Slovak republic

I am trying to set it up here: International -> Locations -> Countries, but it does not work properly.

For example: I choose settings for .SK domain and I leave just Slovakia enabled.
After this I switch to settings for .DE domain and I enable Germany + Austria.
I come back to settings for .SK domain and I have Slovakia + Austria enabled.
When I enable every country under .EU settings, it enables all countries for all domains. 

Long story short: no matter which store I choose (or I select All stores), it uses current settings for all stores.

Am I doing something wrong or am I facing some kind of bug?

Do you have that deep pocket to be able to afford a campaign over all those mentioned countries? 
Usually the shops conquer their country first, then they collects funds or find partners to go internationally.

Anyway, to find out what is going on: you need to give more details on the shop, the theme. If new (most likely) or an older shop.

As I mentioned in my first post (after edit), I have PS 8.1.5

Theme - Bambinis (https://addons.prestashop.com/en/kids-toys-themes/27914-bambinis.html)

But IMHO it has no connection with theme.

Should it work by default as I wish?

It is a fresh installation with some minor changes yet (e.g. theme, tax rules, languages, currencies…). No hardcode changes. But the very first installation was 8.1.3, then update to 8.1.4 and then to 8.1.5 (using 1-Click upgrade).

 

//edit - I sorted it out through DB - deleted a few lines in ps_country_shop
