Windows 10 mobile 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 properly? 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.
