Page format and templates

Hi thank you in advance and compliments for this useful and complete plugin.
Unfortunately I’ve a little problem,but I’m sure you’ll find a trick to help me.
I’m using TML with Avada template. Avada has a particular structure of pages as it use its own page builder. When I use TML it creates the login, register, etc.. pages but everything is in that pages is seen as “body” css also if I’ve an h1 title.
(you can finde here a pge: https://www.profad.it/cnsd/login/)
So everything is in that page is formatted as “body” loosing alla Avada and CSS settings.
How can I do to solve it?
Kindest regards
Antonio
