I′m not sure but I don′t think the problem is with my plugin as:
1. I have tested the script on a test site here and it works:
https://northerntouch.org/activity/
(note for those looking in future weeks it may not work as I use this site for testing etc)
2. When I look at your debug consol you are getting hover 20 of errors. In fact it looks like the service worker from the suoperpwa plugin is hanging (and service workers can interfere with loading of assets)
3. The filter you mention is not native buddypress functionality anyway.
Some things to check though
1. Make sure you are on the latest version of my plugin
2. Use single quote for the code (the code you pasted as typographical quotation marks), this might be an artifact of copying and pasting though.
3. deactivte your other plugins and use standard buddyoress and a basic theme.
As I said there are so many rubbish plugins and themes out there that can caue dowstream plugins so debugging these thinsg is tricky.
