I updated to 5.1.1 this morning and didn’t consider that could be the issue. the blog states a fix to the repeater field.
“Field group: Fixed bug where sub fields were deleted when moving a repeater field to another group”
Perhaps that same fix is causing deleted fields to display null content. I poked around to create variables
$title = get_sub_field('accordion_title' ); // get the title $content = get_sub_field('accordion_content'); // get the content
That results in a 0 instead of empty space. Different error same problem the variable is empty.
