Wordpress standard uses tthe ‘vertical-align:top’ for all overviews (pages, posts).
On mouse-over the link edit/delete/etc are shown right below it.
ACF 6 centers all content in de the middle of the TD.
Please change the css to
.acf-admin-field-groups .wp-list-table tbody th, .acf-admin-field-groups .wp-list-table tbody td {
vertical-align: top;
}
