Calculation of costs for duration task in delayes scenario incorrect

[ScrapmetalEngineer]

• The project has two scenarios: plan and delayed.
• I have two nested tasks within one higher-level task.
• One of the tasks has an effort with a limits property only in the delayed scenario
• if I evaluate the project costs for the plan-scenario, the cost of the passingTask is 0 as expected.
• if I evaluate the project costs for the delayed-scenario, the cost of the passingTask ist 4800, which cannot be true, due to a lack of effort.

Here is the result:

A possible workaround is to assign the chargeset costs not to myTask, but to someotherthinggoingon

I have a simple test file to show the bug:

project I144 "Testproject" 2024-02-14 + 20m {
	timezone "Europe/Paris"
	timeformat "%Y-%m-%d"
	numberformat "-" "" "." "," 1
	currencyformat "-" "" "." "," 1

	currency "EUR"

	scenario plan "Plan"
	{
		scenario delayed "Delayed"
	}
}

account costs "Costs"
account rev "Revenue"

resource test "Testing" {
	rate 640
}


task myTask "Meaningful Thing" {
	allocate test
	chargeset costs

	task passingTask "Just some time to pass" {
		duration 3w
		purge allocate
	}

	task someotherthinggoingon "Some other" {
		delayed:limits{dailymax 4h}
		effort 2w
	}
}

balance costs rev

navigator navbar {
  hidereport @none
}

textreport test "test" {
  header -8<-
    == Accounting Software Project ==
    <[navigator id="navbar"]>
  ->8-
  footer "----"

	scenarios plan, delayed

	taskreport overview "Ueberblick" {
		columns bsi { title 'WBS' }, name, start, end, cost, effort, chart { scale week width 5000 }
		# For this report we like to have the abbreviated weekday in front
		# of the date. %a is the tag for this.
		timeformat "%a %Y-%m-%d"
		hideresource @all
		loadunit days
#		rolluptask (treelevel() = 1)
		caption 'All effort values are in man days.'
		sorttasks tree
		formats html
	}
