Your browser caches old redirects. It may be fixed and you wouldn’t know it.
Open chrome dev tools CTRL+SHIFT+I, click the networks tab and then checkmark disable caching.
Try accessing your new redirect with dev tools open and see if it works while ignoring the cache.
If that still doesn’t do it, see if you’ve missed some important escape chars. I’m thinking the / just before your wildcard group might need to be escaped.
