Guild Wars 2

I am not sure if this is the right place to post this, but please move if not….

Today I wanted to do a dungeon and went to look for party in LFG…

First I joined party for SE and when I tried to enter I got Network Error, then tried to join CoF party and got the same Network Error…
(I posted about that Network Error here already:
https://forum-en.gw2archive.eu/forum/support/bugs/Dungeons-and-Network-Error/first#post5325332)

But after a bit of talk with people in party I joined, I realised that they were from Sorrow’s Furnace, NA server, while I am from Gunnars Hold, EU server so we cant play together….

My question is why is that possible for me to be able to join NA parties from LFG?
Shouldnt it be seperated since we cant play together…
Maybe its just LFG tool bug that needs to be fixed so am posting here…

I am gonna bump this because I just joined two LFG groups and both were from NA so had to leave…

Few people told me that same thing is happening to them too so wish I could get some feedback on this…

EDIT: MY search for party continues after those two groups I joined…
I joined 5 more parties and all of them were from NA even tho I am from EU so had to leave all of them…
