Hi raindi,
Thanks for posting in the Community!
At the moment we're unable to retain the columns you have selected in the Projects tab. I replicated the situation you have mentioned and got the same results when going to a different tab and went back to Projects tab, the columns goes back to the the original settings.
I'll take down of this as well so that I will be able to personally send this over to our engineering team. I recommend also sending your product feedback through your QBO account under Settings icon or Cog wheel, and select Feedback.
You can also check this link to learn more about: Set up and create projects in QuickBooks Online and Accountant.
Please feel free to add a comment below if you have other concerns about projects in QBO. I'm always ready to help. Take care, and have a great rest of the day!
