Hi,
I used the module for a normal content type form with some fields and a field collection as well.

When I do not fill my required fields and submit the form... everything is like it should.
(The required forms ar marked and a error message is shown above)

BUT when i try to create a new node and fill some fields, add another item of my field collection (for example I have now 2 rows - multiple values are possible) and forgot to fill all required field, is all CSS broken after clicking the save button.

It looks like the arrange fields js is not correct attached to the form.
