Windows 10 mobile (and Windows 10) email question - the enter key

I have a windows phone 640 that came with Win 8.1 and I upgraded it to Windows 10 mobile via upgrade advisor.

In Windows 10 mobile, in the email app, when I get to the "to" field, and enter the recipient, if I then press the enter button on the keyboard to move to the next field which is Subject, the cursor does not progress to it. I have to physically tap it there to move it to subject. Pressing enter will move the cursor from Subject to body, just not from To to Subject.

I windows 8.1, it does progress to the subject field when I press enter.
Anyway to get it to work like this? I did restart the phone and the Windows 10 mobile is a reset version and everything works good.

It is Windows 10 mobile version 1607 build 10.0.14393.953

Thanks.

Interesting. It doesn't work in the Windows 10 desktop mail app either.

On the phone it is annoying since it slows things down since you have to stop and move/tap the cursor physically with finger instead of just entering though I suppose you could just tap again after tapping to enter the recipient. I guess I am just used to using the enter key to move from field to field.
