Hello,
we have the same problem. We have two installes languages and both of them are content languages. We created two menus, one for english and one for hungarian language. And created two menu modules for them. Language Filter plugin enabled, and Language switcher module assigned to the languageswitcherload position. We tried that no enable Language Filter plugin, and no publish any Language switcher module, but we saw only one menu. Now we can see the two menus, but only call from url. The flags on the languageswitherload position are missing.
Please help to solve this problem.
Thanks
