Help, can't get WPML and Geodirectory to work together

Hello everybody, obvious Noob-question here. I’m trying to set up a bilingual Globaldirectory database for Classic Car related businesses. Install was a breeze, and before installing WPML everything worked fine. After installing WPML and translating the necessary pages everything seemed to work fine, but the Dutch version doesn’t show any listings when the search field is left empty, or if you only search by category. However, if you search for a specific name, you do get the right result. What am I overlooking here? And yes there are several translations in the Places database available. The site can be found here: http://www.classicproof.com/greasemonkeys
It’s still a mess translation and otherwise, but I wanted to get the thing working first before I spend hours straightening those things out. WPML, WordPress and Geodirectory are all completely up to date.
