MOE: Changing guardian one to two

 This month January 2021, parents been request to login to update the information of guardian on the MOE website. I notice there's changes of change of guardian one to two. I registered for my sons, using my name and my guardian I had put up my hub account in the first place. Then I see in second guardian is myself that was since registration from the first day. 

This month I login to update as per request by teachers in school of primary and secondary school. Suddenly I see that my name on guardian two has been request to click as guardian one. So I did that click to change, then I need to click again for guardian two for my hub as second guardian. I don't understand why need to change like that.I done for my 2nd son then I went update for my eldest and it is also the same. 

That's not all, it's also important to click the small square on the last page of personal details.  Basically mean if saw there is red letters on the page, those links need to be click and checked.

Why need to choose of guardian one and guardian two? It's quite complicated don't you think?
