Hi @Denis_MLoan, I'm so used to pressing 'enter' after each change that I didn't realize this happened. This is definitely a bug, but not a new bug. 
I went back in time, all the way to our release version 3.33 and I found it there too.
We created a bug report for this issue. We'll update you here when it's fixed. On the meantime, we may have to train our end users to press enter after each edit.
