if ( ! empty ) returning blank fields rather than else content

Just noticed I had that UL in the wrong place, but still having the same problem:

	// Event Coverage

	$coveragegroup = rwmb_meta( 'cf_coverage' );

	if ( ! empty( $coveragegroup ) ) {

		echo '<div class="eventcoverage">';

		echo '<div class="coverage">';

		echo '<ul>';

		// Call Coverage Data

		foreach ( $coveragegroup as $coveragedata ) {

			echo '<li>';
			echo '<a href="' . $coveragedata['cf_coverageurl'] . '" target=_blank>' . $coveragedata['cf_coveragedesc'] . '</a><br>';
			
			// Coverage Date

			$thecoveragedate = $coveragedata['cf_coveragedate'];

			if ( ! empty( $thecoveragedate ) ) {
			$thecoveragedate = $coveragedata['cf_coveragedate'];
			$getcoveragedate = date( 'jS F Y', strtotime($thecoveragedate) );
			echo '<div class="coveragedate">';
			echo $getcoveragedate;
			echo '</div>';
			}
			echo '</li>';

		}

		echo '</ul>';
		echo '</div></div>';

	}

	else {

		echo '<p>No coverage found</p>';

	}

function cf_events_register_meta_boxes( $meta_boxes )

{
    $prefix = 'cf_';

	$meta_boxes[] = array(
