Highlights not working in "class" property

Is really rare.

This is my code for listing jobs:

[job_loop]
<div closing-date="[job_field3]" job-categories="[job_categories]" class="jobs-manager-list-container clearfix row nomargin [job_highlighted]">
	<div class="jobs-title row nomargin">
		<div class="job-icon-container">
			<img class="job-icon" src="https://www.earlychildhoodireland.ie/wp-content/themes/ECI/images/job_employer.png"/>
		</div>
		<h1>[job_title]</h1>
	</div>
	<div class="row nomargin job-row">
		<div class="jobs-panel-left col-xs-12 col-sm-12 col-md-10 col-lg-10 nopadding">
			<div class="col-xs-12 col-sm-4 col-md-4 col-lg-4 nopadding">
				<div class="jobs-col">
					<div class="job-icon-container">
						<img class="job-icon" src="https://www.earlychildhoodireland.ie/wp-content/themes/ECI/images/map_marker_orange.png"/>
					</div>
					<div class="job-info-container">
						<h3>
							[job_field4_label]
						</h3>
						<p>
							[job_field4]
						</p>
					</div>
				</div>
			</div>

			<div class="col-xs-12 col-sm-4 col-md-4 col-lg-4 nopadding">
				<div class="jobs-col">
					<div class="job-icon-container">
						<img class="job-icon" src="https://www.earlychildhoodireland.ie/wp-content/themes/ECI/images/job_house.png"/>
					</div>
					<div class="job-info-container">
						<h3>
							[job_field6_label]
						</h3>
						<p>
							[job_field6]
						</p>
					</div>
				</div>
			</div>

			<div class="col-xs-12 col-sm-4 col-md-4 col-lg-4 nopadding">
				<div class="jobs-col">
					<div class="job-icon-container">
						<img class="job-icon" src="https://www.earlychildhoodireland.ie/wp-content/themes/ECI/images/calendar.png">
					</div>
					<div class="job-info-container">
						<h3>
							[job_field3_label]
						</h3>
						<p>
							[job_field3]
						</p>
					</div>
				</div>
			</div>

		</div>

		<div class="jobs-panel-right col-xs-12 col-sm-12 col-md-2 col-lg-2 nopadding">
			[job_link]<p class="btn-job-more">MORE</p>[/job_link]
		</div>
	</div>
</div>

[/job_loop]

[if_job_page_count]
<div class="job-nav">
	<div class="previous">[job_page_previous_link]Page [job_page_previous_number][/job_page_previous_link]</div>
	<div class="this">Jobs [job_page_minimum]-[job_page_maximum] of [job_total]</div>
	<div class="next">[job_page_next_link]Page [job_page_next_number][/job_page_next_link]</div>
</div>

[/if_job_page_count]

if I try to put “[job_highlighted]” out of “class” print “Highlighted” perfectly, however if I put in the code as it is (in “class”) does not work!
Until a few days ago it worked perfect..

Any idea?

Thanks!!!
