WebCore local server, But cant add statement

I have a local server running on docker on my synology. I registered the browser etc. I create a new blank piston but when I click to add statement, I get nothing.
Thoughts?

ensure you are using the proper repo for the webCoRE IDE (web) files.

Ensure you logout in your browser, clear caches.

Note 2 in the main webCoRE thread has info on this.
