IntelliJ Kotlin Run Configuration, save before build

I have recently upgraded from 2018.3 to 2019.3. Previously when I ran a saved Kotlin configuration with "Build" before launch, the IDE did an automatic "Save All" so that the latest changes to sources were used. Now this appears not to happen, so I run with out of date code - this can be dangerous as I am executing code that I did not intent so the results can harm my database.

Am I missing something? How do I force a "Save All" before the build without having to remember to press Ctrl-S first?
