How do I report TM30 online without encountering errors?

On line TM30 reporting

11 January 2020 successfully applied for registration to report tm 30 online.

Received login credentials immediately.

Did this in my GF name as it is for her house.

Today I went to login was asked to change password...did so successfully. Gf gave me login details.

Have just spent better part of one and half hours trying to input my information.

When I try to save I get Error message saying IMPORT DATA IN SEQUENCE (1) Is incorrect .

I cannot for the life of me figure out what they are referring to. I have double checked all my information. It is correct.

There is a section at the beginning that asks to IMPORT DATA FROM EXCEL FILES: then a box which days CHOOSE FILE then next to that it says No File Chosen.

Then a blue button saying IMPORT EXCEL.

What excel file are they asking for?

Has anyone registered their TM 30 through this portal? And perhaps can suggest what I might be screwing up?

Just to be clear

This is not the App

This is online with the Immigration Bureau.

Feeling frustrated as I need to do this before midnight tonight. 12 Jan 2020.

Many thanks in advance if you can help.

Last query

I input #4 (NON-1 YEAR) as my visa type. It was the only one remotely close to my non immigrant OA.
