"Fade in by line" title animation preset not working

Hi, I'm using Premiere Elements 2020.

I've been trying to get the text to animate using the preset, "Fade in by line", I followed all the instructions on this page: https://helpx.adobe.com/premiere-elements/kb/unable-apply-text-animation-presets.html

But it still won't work. Even though it allows me to "apply" the desired preset, it just fades in all at once instead of line by line.

Any help would be much appreciated.

Thanks
