I've mentioned this before a year or so ago... thought I would mention again as till doing it and it's very frustrating. It's an issue with all the little sliders;

When you go to say turn off Billable (the little slider with the purple dot), every time it slides back to on - but usually it does it as you are saving so you then have to open it up and turn it off again.

If you do it very very slowly and carefully, and make sure you very carefully don't move the mouse anywhere near it after you've turned it off it stays... but the problem is that the save button is to the right and below the slider so you have to be extremely careful and it's very easy to forget this when you are in a hurry to meet deadlines and it slows something down that should be very quick and efficient. It happens in the agreements area as well but it's less frustrating as only have to deal with it occasionally - not many times throughout the day 😊
