[Bug] weekend work not working

[madeline007y]

What happened?

sorry for the absurd amount of screenshots, i'll walk you through all of them (also i sincerely hope this isn't just user error)
A) experiment: grow fungus for four days, from friday - monday. made experiment, said it lasted four days; couldn't yet specify that weekend work was OK, so the experiment went from 6/19 to 6/24
B) went in to edit experiment, said "weekend work ok." saved change; still said "6/19 - 6/24" on the calendar and in the experiment description
C) changed from 4 to 2 days; didn't update the "weekend work OK" setting yet. saved change; said experiment goes from 6/19-6/22 in description and on calendar (so now it's four days, with two of them being the weekend days)
D) turned off "weekend work ok," saved, no change in the experiment timing

What did you expect to happen?

when i clicked "weekend work ok," i expected the four-day task to run from 6/19 - 6/22 (four days total) instead of 6/19 - 6/24 (four weekdays)

Steps to reproduce

1. made experiment, said it lasted four days
2. went to "edit properties" in the experiment and said "weekend work ok"
3. saved the change, closed the popup
4. saw no change so refreshed the page, still no change
