Really a low priority, but very irritating for OCD. I think this cropped up in WP 4.3.0.
The paragraph of a message field has top margin that makes it inconsistent with every other field. This may only apply to left-aligned labels.

Explanation, if it isn’t obvious: http://i.imgur.com/hC74jV6.jpg
Can be fixed with this CSS:
.acf-field-message td.acf-input > :first-child {
margin-top: 0;
}
.acf-field-message td.acf-input > :last-child {
margin-bottom: 0;
}
Thanks for the bug report, I’ll see what I can do about reporting it to the developer
