Save Preset on Dynamics Screen No Text Input

I think I ran into my first bug with Studio 20 beta.
When I click "+" to make a new preset and choose the option to make new preset, I get the field to fill in the name of the new preset. However, I cannot type anything. The field seems to have a read only property.
