Unable to Configure an index pattern (Kibana 4.5.3)

Lukas - it happens every time I type something in, anything in at all, but only once I've finished typing and press return. There's no Create, or Okay button or anything like that either.

EDIT: I was wondering whether Kibana has extracted correctly. I was wondering if there's a way to check.

EDIT #2: I've found this thread which shows what the 'Configure an index pattern' screen looks like for me;

...although in the top left under 'Index patterns' it says;

Warning No default index pattern. You must select or create one to continue.

....but then lists;

...under it.
