Edit Properties dialog shows only 5 of 7 values of a property

From AKSW/OntoWiki#277

It seems that the Edit Properties dialog is limited to show only 5 values of one property even though there are more. I thought maybe the "is large" option of the knowledge base configuration is supposed to solve this but checking it makes no difference.
Example: see the first screenshot - there are 7 triples of "AllianceHealthcare gr:offers **", but only 5 of them is displayed in the Edit Properties dialog in the second screenshot. (Also, for some reason the gr:offers property is displayed twice there as "gr:offers" and "offers (0..)" even though it is the same property, but I can live with that.)
