Hey! It’s a known issue with the 2017.2 beta, a fix is on the way very very soon.
Just want to check that you’re not seeing this on 2017.1?
Hey, the problem exists on 2017.2.ob3 and 2017.2.ob6. I believe 2017.2.ob3 had the settings but they couldn’t be added (the newer only has 1 setting).
I don’t have the 2017.1 version so I can’t say for sure.
I’ve just checked and the fix is coming in 2017.2.0b7 
(and also is not present in 2017.1)
And it’s just a mess with the UI… no data/settings have been lost.
