ACF fields from posts Article1 and Article2 are inserted below using 2 different grid layout plugins

The two widgets successfully fetch select ACF fields from the two posts.
In both cases  the source posts' ACF fields do NOT get mixed up with this destination pages' ACF fields.
They manage to pre-process the shortcodes contained in fields, in some way, before they reach this destination page.
