The URL field can not be cleared in a Field Label on a table extending TaskDescriptionIt is not possible to clear the URL field in a Field Label on a table extending Task for a field from the Task table.Steps to Reproduce 1. Set URL on Priority label under task table.2. Remove the URL value for Priority label on the task child table (like: sn_si_incident).3. Go to any task record, the URL is displayed correctly (The one defined on step#1).4. Go to any sn_si_incident record and the URL displayed is the one defined on task. WorkaroundAfter carefully considering the severity and frequency of the issue, and the cost and risk of attempting a fix, it has been decided to not address this issue in any current or near future releases. We do not make this decision lightly, and we apologise for any inconvenience. The workaround is, on the child task level (on this example under sn_si_incident), create an OnLoad client script to change the label from URL to regular label: function onLoad() {var colorLabel = g_form.getLabel( 'priority' );colorLabel.outerHTML='<label onclick="return labelClicked(this);" for="sys_display.incident.priority" dir="ltr" class=" col-xs-12 col-md-3 col-lg-4 control-label"><span id="status.incident.priority" aria-label="" data-dynamic-title="" mandatory="true" oclass="" class=" label_description"></span><span title="" class="label-text" data-html="false" data-original-title="Sequence in which an Incident needs to be resolved, based on impact and urgency">Priority</span></label>';}Related Problem: PRB609377
