Shouldnt Kumoko have a new key?

[Bernkastelll]

Let me explain, as we can see, her profile currently has 2 keys, the 7-A and the High 6-A, however, between these 2 keys, it lasted more than 2 years, and during these 2 years, her ratings were literally Human Level, as stated by herself MULTIPLES times, she was weak, could be sick very easy, her skin could burn due contact with sunlight, she had literally 0 powers and all, it was because the process of development from an Arachne (7-A) to Goddess (High 6-A) was made by a troubleful way, which made her be powerless like a normal human for literally more than 2 years.
