For example, if I set the period of ISV to 2020.05.05~2021 09.05 in the process of dividing parts such as ISV1, OOS1, etc.,
If I click the calendar directly instead of 2020.05.05, and modify myself it to 05.01 date, etc.,
The builder itself will refresh and return to the first main screen.
In this case, when ignoring and proceeding with the work, a window such as warning and x appears on the bottom screen of the Builder, and an error appears.
Please correct it after checking this part.
