Warning info message when save schedule task

This message appears when I tried to save a schedule task from systemsettings in Plasma.

The error says that your new task is invalid, because it has a bad day-of-week.

What exactly was the scheduled task you tried to enter?

Status: NEW => NEEDINFO
CC: (none) => marja11

The assigned task is to execute a bash bin file, at a specific time every Tuesday of every month of the year. 

I just tried to schedule another task, which runs for example Konsole and it gives me the same error.

In fact, I get the same error with any configuration I choose...

Looks like a invalid config from your side (as the error message already states)

You are missing the 5th field (day-of-week) in your config.

Crontab Entries:
All crontab entries [made with crontab -e] have this format, per the man page:
1: The Minute of the hour to execute [command]
Range: 0-59
2: The Hour of the Day to execute [command]
Range: 0-23 3: The Day of the Month to execute [command]
Range: 1-31
4: The Month to execute [command]
Range: 1-12
5: The Day of Week to execute [command]
Range: Check your man page, could be 0-6, 1-7 or 0-7
6: command to execute

That's great as a workaround, but he wasn't using crontab, but the Plasma Task Scheduler. See the attached screenshot for an example.
It fails for me, too, I can't press "Apply", but that might be user error. I never use this tool, but use crontab instead.

Good afternoon. 

I have verified that activating every day of the month does allow me to save the task without error, but it does not execute. Furthermore, it should allow you to save only the day of the week that you want it to be executed, if not, what is the point of that section?

This is my terminal output:

I have verified that: 

- If I mark every day of the month, every day of the week and the specific day of the week, for example Tuesday. The task is saved correctly but it is not executed, regardless of the time (I have tried restarting the computer as well). 

- If I mark every day of the month only, the same error appears and the task is saved.
