HTTP Requests from deleted plugins

Hi! I'm seeing an issue where plugins for 3rd party software plugins that I have uninstalled are still making calls http requests during page loads.

Specifically:
https://js.gleam.io/5nrHF/ol.js
https://ssl.luckyorange.com/w.js

Any idea how I can remove the code thats making these requests? Again, I uninstalled the plugins from the wp-admin area.
