After editing a list in Isolation Mode, and making any changes to the Properties, the Preview Values are dropped. This results in an unreadable view as shown:
Only by setting the Preview value again does it show correctly:
This is quite tedious when changing the properties constantly, and having to go reset all of the Preview values to get an idea of what it looks like. Thanks!
