Trial period in Protect Content says a wrong fee for the subscription


I have some memberships with a 1 month trial period.

Now when a new user sign up for them Protect content invoice says:

You will pay EUR 0.00 each year.
The trial period of one month is for free.

and it is not correct, the user will pay EUR 120 each year and ONLY for the first month EUR 0

This error can get us in legal troubles with the customer, how we can fix it?
