Basic Conditional Build Tag Expressions Unavailable in RH Classic
I'm using RH 2019 Classic (14.0.12.0).
All of my conditional build tag expression definitions in my HTML5 outputs have been switched to Advanced (I was only using Basic before) and I can't switch them back. Not only that, they're wrong.

In the picture above, the red box shows that the Basic radio button isn't active.
If I create a new definition in an existing output, I can build it using a Basic expression and save the expression, but I can't apply it.

In the picture above, the Update button never becomes active for the new expression.
In fact, trying to update the conditional build tag expression for any existing output won't work. The Update button never becomes active.
If I create a new output with a new conditional build tag expression, I can build it using a Basic expression, save it, apply it to the output, and still edit it as a Basic expression.
So, in all of my existing outputs, all of my conditional build tag expressions are using Advanced, they're all wrong, I can't switch them to Basic, and I can't apply a new expression.
Am I going to have to rebuild nine outputs and conditional build tag expressions?
