First time user – can not enter room

Hi there!

I am a new user, working on my localhost on my site.
I installed 2 and 3 times the plugin and although in the WordPress I can see the new menu of ‘WP Hotel Booking’ unfortunately I do not see a menu “Room” (like in the screeshots you have in the plugin page) in order to enter my rooms.

Am I doing something wrong or is there an incompatibility with WordPress 4.9.4 ?

Thank you
