[Plugin: WordPress SEO by Yoast] Duplicate title tags – www.intovintage.co.uk

Hi, Im getting duplicate title tags

<title>
into vintageintovintage | Into Vintage</title>
Followed by:
<title>into vintage</title>

Also the interior page

<title>
Bracelets & Bangles | intovintage</title>
and
<title>Bracelets & Bangles Archives – intovintage</title>

How do I stop this from repeating?
