After Update Trigger Not Firing After Workflow Field Update


When an order is created in our org, it automatically submits into an approval process about 7 minutes after creation.
When the approval process is initiated, there is a field update that occurs to fill in the date/time of submission.

I have a trigger that should unlock the record when an update occurs, but it is not firing during the above mentioned automation.
It works perfectly when I manually edit the record.

Here is my code. Am I missing something to make it work when there's a worflow action triggered update?

I'm not a developer, so I don't know much.

trigger Unlock_Order_Pending_Approval on Order (after update) {
//Get records to unlock
List<order> orderList = [SELECT Id From Order WHERE EffectiveDate = TODAY];
//Check locked records
List<order> orderLockList = new List<Order>();
for(Order c :orderList){
//Unlock record
    //Unlock records
    List<Approval.UnlockResult> ulrList = Approval.unlock(orderLockList, false);
    // Iterate through each returned result
    for(Approval.UnlockResult  ulr : ulrList) {
        if (ulr.isSuccess()) {
            //Operation was successful, so get the ID of the record that was processed
            System.debug('Successfully locked account with ID: ' + ulr.getId());
        else {
            //Operation failed, so get all errors                
            for(Database.Error err : ulr.getErrors()) {
                System.debug('The following error has occurred.');                   
                System.debug(err.getStatusCode() + ': ' + err.getMessage());
                System.debug('Order fields that affected this error: ' + err.getFields());

When the approval process is initiated, does the field update happen on the order object? Are your system debugs getting printed in the logs?
