Editing Expressions in Rule Machine Broken

Editing "while expressions" can end up in dead end where rule needs to deleted.

To reproduce:
Create new rule
Create repeat while expression
Edit repeat while expression
Select AND from drop down box
Select New Condition from drop down
At this point the rule becomes unusable and needs to be deleted

Also can't change existing condition while editing expressions (while or if/then)

I was able to reproduce the first issue with the steps provided:

As it relates to the 2nd item, I think this is expected functionality. To edit the existing condition, you need to go to the “Manage Conditions” on the bottom of the screen. Otherwise, you can insert or delete parts of the expression.
