I think the issue here has to do with the MERT configuration. When you use lattice input, the weights on the lattice edges are included in the translation model as a feature that MERT can optimize. I'm not familiar with the MERT optimizers that are included with Moses, but it sounds like it is expecting that you configure a range of possible values you expect the feature to get. Hope this helps... --Chris
