Enter Key No Longer Moves to Next Sub-Task

Hi, I noticed that as of recently (I was out of town so could have been in the past few weeks) when I create a task and start entering sub-tasks, the enter key after typing a subtask closes the task. I preferred the previous behavior where the enter key would start the next sub-task. This is very helpful when I have a new project and can just enter a bunch of things that have to be done. If the behavior won't be changed back, is there another key that would do this? I tried tab but it didn't work.

Thanks!
