Please follow the steps given in this article to retrigger the activity in the LRS to send back data to WordPress triggers again.
If you see passed/failed verb statements of xAPI content in the LRS but on WordPress, the lesson/topic/quiz associated is not completed or you do not see reports data in the GrassBlade > Reports.
In this case, you can find the xAPI Content activity in the Error Log or Activity Stream and try to retrigger it to resend completion data to WordPress in case it was not received for some reason.
In GrassBlade LRS, go to Reports > Activity Stream from the left sidebar.
Click on the filter icon to select the filters to generate report data
Select the xAPI Content and User (Do not select if you want to see all users). Also, select the “completed” or “passed” verbs to clean the data.
In most cases only the “passed” or “completed” verb is used to complete the associated activities in WordPress. You can select others as per your setup.
Click the Filter button.
Now, click the  icon to expand a specific activity of a user and click the Re-run Triggers button.
