Hi there,
Very odd, no reason why I can see that this would occur because of that plugin. In cases where it works fine up until WPML is used, we usually refer users to post on their support forum. The theme has been certified by the team there as 100% compatible, so the usual process is for them to test the issue and if we need to change anything, then we do. You can get support from them here: http://wpml.org/forums/forum/english-support/
Thanks,
– Ed
