The large size has been mistakenly sealed up until now

The large size has been mistakenly sealed until now, one of the help is asking how GM is doing, and the other one tells me that I am reviewing it, which has been mistakenly sealed for nearly 4 months.
Large size: CHDCA Otichoda

I don’t even know what to do

Is this some kind of riddle

Posted in the wrong game, perhaps ?
