hi!
Is it uni-title or uni_title? Make sure those match since you’ve written both in your description..
It should not matter what template you’re using it on, but I guess that depending on where in the template you use it you might need to provide the post id as well.. try this:
<?php global $post; ?>
<h3><?php the_field('uni_title', $post->ID); ?></h3>
