WP multisite ACF get_field() restores to current site

I'm getting really frustrated with this issue I am having with WP multisite.

The idea is, I have a multisite and it is here where all posts are created then just shared down to the other sites using ACF field.

Here is a part of the code where the issue happens:

switch_to_blog(1);
$person= get_posts( $args );
foreach($person as $post) {
     echo get_current_blog_id();     THIS WILL DISPLAY 1
     $person_info = get_field('person_info', $post->ID);
     echo get_current_blog_id() ;    THIS WILL DISPLAY THE CURRENT SITE, THE SITE JUST GOT RESTORED
}
restore_current_blog();

Can anybody help me figure out what is happening please? TIA
