global-site-search displaying caption ID

I have an issue with global site search. All the results display fine except the result set displays the caption id code (example below) as if its missing some code or there is a syntax error

Test search results display this an example:

Test with taxonomy<br />

[caption id=&quot;attachment_17&quot; align=&quot;alignleft&quot; width=&quot;300&quot; caption=&quot;Caption to test SUP review&quot;][/caption] test SUP review with taxonomy test (More)
