directory plugin - slug and display issues

hi,

i am having the following issues with the listings/directory plugin, please see the urls for examples.

- i cannot find how to change the slug from 'listings', to 'directory'. i have edited the slug of the page but this has made no difference, /directory redirects to /listings. http://bearwood.lokel.co.uk/directory
- there is no page title displayed in list view. http://bearwood.lokel.co.uk/listings/
- i have strange text above the title block. 'ListingsListings'. http://bearwood.lokel.co.uk/listings/
- listing detail. can the map be set to a percentage width so it is responsive? http://bearwood.lokel.co.uk/listing/t-c-hayes/

wpmu have been granted support access to the site.

thank you.
