This “loading presets…” screen means that the web application is waiting for the data to be received from the cloud based database. Given your other post (Bad lua code logs you out of app?) I’d suspect that something is not quite right regarding the networking.
Please note, the connection is established between your browser (as the client) and the Google’s Firebase cloud database (the server). There is no Electra One network infrastructure in between. If you do not see any requests sent out, something might not be right on the browser side. Looking at the screenshot you shared, you seem not to have even all CSS stylesheets loaded either.
