In the search options I have an option to search for 1→1 related stuff.

However, it doesn't work. I have a drop down, but the entries are broken. I can't take a screenshot of an open list, here is the source code:

<option>|2:Meitner</option>
<option> Liesel|</option>
<option>|1:Müller</option>
<option> Paul|</option>

But it should be

<option>Meitner, Liesel</option>
<option>Müller, Paul</option>

Another instance is an ID. This one doesn't get cut at the blank space but still doesn't work and comes with ":" and "|"

<option>|1:1|</option>
<option>|2:2|</option>

  And it doesn't yield a result either.
