When you display the data for flex fields you shouldn’t be trying to get fields that aren’t associated with that particular layout.
$layout = get_row_layout();
if ($layout == 'layout_1') {
// show fields associated with layout 1
} elseif ($layout == 'layout_2') {
// show fields associated with layout 2
}
Just a basic example, could be far more complicated depending on what you’re doing. For example if 2 layouts have some fields in common then there might be function calls for those groups of fields.
