You mix different steps.

The Filter only reduces the list of possible candidates in all your loaded tracks.

For the reduced/filtered tracks you apply the Action.

The regular expression itself is the part  
`'.*\((.*)\)'`  
~~or~~  
~~`.?\((.*)\)`~~

@ohrenkino's syntax  
`$regexp(%title%,'.*\((.*)\)',$1)`  
is - as written - for Convert Tag -\> Tag
