Can’t manage with User plugin

Hi,
Can’t manage with User plugin.
1. Can’t see registration form on my accommodation page (reservation asset)
2. Do not have prompt for registration during reservation process
3. Can’t manage with dashboard: first on my ForCustomers page (customer dashboard
) was login form. But there was only menus, which modules assigned on all pages. After I tried to login as superuser, I’ve got en error “The requested page can't be found.”
Could you pleas help me?

Hi,
Thank you very much for help. I did not use Falang yet, but I’ve created new window without any assigned modules for my customer dashboard page and it is ok now. But I have more questions:
I’ve registered and confirmed link from my mail.
Now in back-end:
I can’t see new customer in solidres customer list (but can see this customer in joomla user list)

Front-end:
If I logged in, I can see list of reservations on my For customers page, but can’t see Profile edit link. If I log out, then go to For customers page and log in, then I can see only Profile edit link.
Is it also because of using Joomla language switcher, or I do something wrong?
