splunk security essentials upgrade problem

[user487596]

Hi everyone! After upgrading to version 3.8.1, I got a bunch of errors:
In the Security Content i get the following: 

app/Splunk_Security_Essentials/security_content 404 (Not Found)Understand this errorAI
web-client-content-script.js:2 Uncaught (in promise) Error: Access to storage is not allowed from this context.

On the Data Inventory page i get the following:
Error! Received the following error: Description Message Error occurred while grabbing data_inventory_products

Traceback (most recent call last):
  File "/opt/splunk/etc/apps/Splunk_Security_Essentials/bin/generateShowcaseInfo.py", line 473, in handle
    if row['stage'] in ['all-done', 'step-review', 'step-eventsize', 'step-volume', 'manualnodata']:
KeyError: 'stage'

There are also a couple of apps: splunk_essentials_8_2 and splunk_essentials_9_0 are both enabled.
Does anyone know how to fix this? Thanks!
