Search terms incompletely transmitted in 'Showly'

[C-O-D]

I'm using an app called Showly which, among other things, provides search links for actor searches and so on.
So, when I start a lookup for an actor over one of the provided links, e.g. Google, DuckDuckGo or Wikipedia I'm telling Open Link With to open the link with my browser but the search term subsequently consists just of the first word of the full name, so e.g. it's looking just for Kiele instead for Kiele Sanchez.
I had no idea what the problem could be until I realized that it worked again after I uninstalled Open Link With.
So the question is, why are the search terms transferred incompletely and why or to what extent does Open Link With intervene?

Best regards
