How can I resolve issues with my TM 30 online registration not saving data?

Hi there! I have an enquiry about the online registration of my TM 30. (notification of residence.) It turns out that today I completed and submitted the online registration of my TM 30 along with all the documents required (passport main page of the tenant, the copy of the landlady's ID, the deed, the rental agreement, the TM 30 as such, and that's it.) I received a username and a password that I changed upon clicking on the link they said. I logged in to the website and I filled out all the sections concerning my visa type, personal details, and all the stuff, and I inserted all the data into the table below, which was added quickly. The thing is that when I logged out and I logged in again, the data that had been added to the table below had disappeared, as if I had not done anything. Although all my personal details and submitted documents are in the 'edit profile' section. But when I search for my TM 30, this one does not appear. So the question is, did I do it well or this website does not work at all?
