Theme my login doesn't style login page

Hi,

After deactivating s2members and activating Theme my login it only styles profile page.

Register page and login page remains as wordpress default pages.
i’ve tried in another wordpress installation and login and register pages styles the same as profile pages.

I’ve reading the documentation for an answer whitout results.

?What i’m doing wrong?
?I need to style these pages manually?

You can see how it looks now in

Theme my login version 6.2.3
Suffusion theme 4.4.3
WP 5.1
Thanks in advance
