Overview of the issue
When you have content that contains <textarea> tag for example
<label for=”description”>Description</label><textarea name=”description” required>
and try to translate it using WPML’s classic translation editor, the editor HTML will break

Our developers are working a fix for this issue. For now, you can use WPML’s Advanced Translation Editor to translate your page.
