I think you’re making things a little more confusing than they are. Lets try simplifying the logic a bit.
Post a screenshot of the actual custom fields inside the field group, please. That way we can get the correct field names.
Start off by checking with a simple conditional if the current page_id is equal to your field.
for example:
<?php $field = get_field('your_field_name') ?>
<?php if(get_the_ID() == $field): ?>
