Deadcool: data are fetched from our copy of MusicBrainz DB (we cannot use directly the main server, we need some enhanced requests and the original server also has strict request limits). The problem in your case is caused mainly because requests are cached also locally. You can force cleaning this cache in File - Manage database - check "Clean URL cache". Then all MusicBrainz requests will be fetched from our server, and should include your recent entries. Our server is synchronized with the original one circa once per hour, so your entries won't be there immediately.
Data from Wiki is mostly read from Wiki links contained in MusicBrainz DB too.
I decreased expire timeout of our local cache to 1 hour, so manual cleaning should not be needed in upcoming versions, after 1-2 hours new data should be fetched automatically.

It seems, there is problem in search indexes, MusicBrainz still does not fully support correct update of search indexes (they say it is not "stable" yet), so manual reindexing is needed after such change sometimes (it lasts ~10 hours) :-/
