How to get form validation working?

[Mr-Idjit]

Is it just me or is the form validation not working?

I can make form validation work on other pages and use a custom made form like {{ form.name(class='awesome_style') }} but every form that has to do with flask-user is not working; /user/sign-in, /user/forgot-password and /user/register in mind.

Is this common? Something I don't know about? .. but most important how do I make the form validation work on these flask-user pages?
