Proxylizer and No IP adreses to select

Hi I'm trying Proxylizer, I followed step by step the guide RouterOS - RouterOS - MikroTik Documentation. The application seems to work but I can not add IP users information, I can only define user name and email, the field IP: is disabled and I read No ip adreses to select with color red somenthing like an error and I have not received any reports, some ideas?
