WDM5.7.1 - Wake on LAN package will remain in Scheduled Packages

I will start Wyse 3020 in the morning using WDM and plan to turn off the power in the evening.
However, it is facing a serious problem!

I have set up a regular WOL package from WDM. （The first will succeed.）
However, the WOL package will remain in [Scheduled Packages] even the next day.
I will not disappear even when I wait...

I confirmed the following.
- With this influence, the next Wake on LAN package will not be sent.
- Packages will not be sent unless you remove the remaining package every time.
- Packages sent in [Real Time Commands] will end normally.

Do you have any solutions?
