Why do I have a code of 2b under December in my 1095C when I was full-time for that month with my employer? Do I need to get a correct one?

Is that a mistake? Should I have it corrected?

Laid off from full time work July 31; lost insurance.  I started employment with the employer August 2021. Insurance started with new employer November 2021.

In line 16, my codes starting from August 2021, is 2D 2D 2D 2C 2B (December).

Also, in Line 14, it says 1E for November but 1H for all the other months, even December.
