Hi and thanks in advance for any pointers here.

Issue:  I created an Action button on the CASE object that calls a Lightning component.  When I click on the Add button, then click the Cancel button, the Add button is no longer there.  I have to click on another tab and then go back to the Case and then the Add button is there.

My component:
<aura:component controller="newCheckRequest" implements="force:lightningQuickActionWithoutHeader,force:hasRecordId,force:appHostable,flexipage:availableForAllPageTypes" >
    <!--This controls the display of the New Check Request action screen, before the New CR screen.  It supresses it.   -->
    <aura:html tag="style">
        .slds-backdrop {
        background: rgba(43, 40, 38, 0) !important;  
        }
      <!--  .slds-fade-in-open {
        display:none !important;-->
        
    </aura:html>  
    <aura:attribute name="cre" type="Check_Request__c"/>     
    <aura:handler name="init" value="{!this}" action="{!c.doInit}" />
</aura:component>

My Controller:
({
    doInit : function(component, event, helper)
    {
       var action = component.get("c.getCase");
       action.setParams({"caseId": component.get("v.recordId")});
       action.setCallback(this, function(response)
       {
        var state = response.getState();
    
       if(component.isValid() && state === "SUCCESS") 
        {
        var  cre = response.getReturnValue();        
                 
            // create method in helper class
            // Putting RT first changes header of the pop up
            var createCrEvent = $A.get("e.force:createRecord");
            var crid=component.get("v.recordId");
            console.log('cre-'+cre);
            createCrEvent.setParams
             ({
                "entityApiName": "Check_Request__c",
                "defaultFieldValues":
                {
                    'Check_RequestRelTo__c' : cre.Id
                  
                }
              });
            createCrEvent.fire(); 
        }
                         
});          
       
     $A.enqueueAction(action);
      // $A.get("e.force:closeQuickAction").fire();
    }        
})

My Helper class: Not really needed, but maybe in the future
({
 toastMessage : function(msg) 
    {
        var toastEvent = $A.get("e.force:showToast");
        toastEvent.setParams
        ({
            title : 'Warning',
            message: msg,
            duration:' 5000',
            key: 'info_alt',
            type: 'error',
            mode: 'dismissible'
        });
        toastEvent.fire();
 }
})

My Apex class: to get the record id

public with sharing class newCheckRequest
{
 @AuraEnabled
    public static Case getCase(Id caseId) 
    {
        //Query fields from Parent record to prepopulate New CheckRequest
        return [SELECT Id,CaseNumber FROM Case where id = :caseId];     
    }
}

Thanks,
Eric
