Team members are not displayed correctly

Hi.

I am using the 4 in a row display style for my team members. I am looping the information from the database. There are missing spots on random places thruout the list. In the attachmets there is a screenshot. Bellow is the code:

		<section id="content">

			<div class="content-wrap">

				<div class="container clearfix">

					<div class="row">
		<?php
		include 'functions/db_conn.php';
		
		$stmt = $dbh->prepare ( "SELECT * FROM clani WHERE status = 1 ORDER BY weight DESC" );
		$stmt->execute ();
		$members = $stmt->fetchAll ( PDO::FETCH_ASSOC );
		foreach ( $members as $member ) {
			$ime = $member ['ime'];
			$priimek = $member ['priimek'];
			$vloga = $member ['vloga'];
			$slika = $member ['slika'];
			
			?>
						<div class="col-md-3 col-sm-6 bottommargin">

							<div class="team">
								<div class="team-image">
									<img src="<?php echo $slika; ?>"
										alt="<?php echo $ime." ".$priimek; ?>">
								</div>
								<div class="team-desc">
									<div class="team-title">
										<h4><?php echo $ime." ".$priimek; ?></h4>
										<span><?php echo $vloga;?></span>
									</div>
								</div>
							</div>

						</div>
	<?php
		}
		?>

					</div>

					<div class="clear"></div>

				</div>

			</div>

		</section>
