So odd. Everything is now displayed properly for both those two new extensions.
Things "normalized" and I have no idea why.
All I did is go in and out of the admin page, loaded it a new browser tab a few times.
As for the Flagrow analytics extension, my error in console is different:
Failed to load resource: net::ERR_CONNECTION_REFUSED
Even after performing following these instructions: https://piwik.org/faq/troubleshooting/faq_147/
My host uses apache servers so I couldn't follow the instructions here:
