Setting 0 percentage rollout looks valid in the UI and is stored in the underlying repo, but the UI then later claim that it is 50%.

Adding the rollout, all okey

After hitting save, it bumps back to 50

Ok to change it to 0 again

Resulting repo

A workaround is to just remove the rollout when we want to set it to 0, so this is just a minor annoyance.

Thanks for a lovely product all in all, we adopted it the other week and it feels like a fundamental shift in how we deploy features now.
