What's the difference?

1, the active modification period of the utility model has expired. If there is an obvious writing mistake, the examiner can send you a notice of opinion, or modify it ex officio, but if it is written directly into another one, it will not be changed.

2. Where an invention is created, it may be modified within the time limit specified in the notice upon receipt of the notice of entry into substantive examination, but the modification shall not exceed the scope.

Generally speaking, once the patent document is submitted, it is very troublesome to modify it, so it must be checked repeatedly before submission. I suggest to find an intermediary to show you, because what is wrong and how to change it should be analyzed in detail.
