iMessage

hey! i’m kinda confused, one of my favorite kpop groups posted their own community number, so basically if they text i’ll get notify by them and others who has their number they will get notify too, and when i get the message they aren’t showing in order for other people it will show the messages in order but for me it isn’t. so i’m confused why the message i get by them aren’t in order when i receive them, so i restarted my iPhone thinking it will work and it didn’t... the picture that i put it shows the message i received them it’s just not showing in order...
