Think of the screen as one large 1920 (24*80) bytes long field.
Before reaching the 2nd line, the cursor will go all the way to the end of the 1st line.
And if there is an unprotected area on the way, it will stop there.
In most emulations, the ENTER key is mapped to "NewLine".
This allows you to jump to the beginning of the next line,
but then the cursor will always (and only) stop at the 1st unprotected area.

As Dick and Marso suggested, just use the Enter / Newline key.
Note: the emulators are pretending to be a piece of hardware: the 3279 terminal. The tab key was a hardware thing... no interaction with ISPF is required. And I think still handled by the emulator and not ISPF. Perhaps you want to configure you emulator keyboard to redefine Tab to be Newline.
