[Plugin: Search API] Page title error

I’m getting a weird problem on the advanced search page when using this plugin.

Basically, it puts the title of the last blog post in the title field at the top of the page, see:
https://www.hgtestserver2.co.uk/?advancedsearch=1

I can’t seem to find any settings for this plugin or see anywhere in the code where I can define what the page title for the advanced search should be.

I also wondered if there was a way to put the advanced search page into a specific page, ie:

https://www.hgtestserver2.co.uk/search-news-and-archives/

I’m using the MySQL search by the way.

Any help would be appreciated
Thanks
Andy
