[wpv-post-title] displays the Post Titles of the results from the query and [types field='custom-field' item='$current_page'][/types] displays a custom field from the page that the View is inserted on.
Now, if the results of the query return more than one result it will display these different results (as expected), but it will also duplicate the [types field='custom-field' item='$current_page'][/types] value so it is displayed the same amount of times as the results from the query using [wpv-post-title].
Is this expected behaviour?
Is there any way I can stop the [types field='custom-field' item='$current_page'][/types] duplicating in these circumstances?
I hope I have managed to explain the above clearly. Please let me know if you need anything clarified.
