Dynavector 17D3 hitting clamp on VPI Scout

Hi, everyone. I've got a serious problem with my new Dynavector Karat 17D3. It was professionally installed and set up on my first-generation VPI Scout table with the JMW tonearm. It works fine until the stylus goes into the blank grooves at the center of the record. Then the side of the cartridge hits the VPI record clamp. Aside from the loud crashing sound this produces, the dealer says that the impact may damage the stylus. For the moment, I'm playing records without the clamp. That's not really a good solution, though, since the clamp performs an important function and is recommended by VPI. Have any of you encountered this problem? Any tips for a solution?
