Splunk Security Essentials mitre_overview Not Loading Correctly

[kprior201_lilly]

I just upgraded my Splunk Security Essentials app from 3.1.1 to 3.3.3. I'm running Splunk Enterprise 8.1.4. When I access the Analytics Advisor / MITRE ATT&CK Framework page, the MITRE ATT&CK Matrix just refuses to load. Has anyone encountered this, and do you have any troubleshooting suggestions?

Hi @kprior201_lilly 

did you try to check the sources again on the security essentials?

I just poked around in that screen, but it doesn't seem to be what I'm looking for. Previously, the MITRE matrix loaded just fine; I have content enabled that should reflect here. The rest of the page loads as well; it's just the one matrix that isn't working.

Hi @kprior201_lilly 

what version of security essentials do you have installed?

Can you share a screen of mitre matrix to check the error?

Regards

It's version 3.3.3; the screenshot is attached to the original post. It doesn't give an error at all, it just doesn't display the matrix. When I look at the Job Inspector, there aren't any errors, either.
