Scrolling text in ver 20.09

Hello ;
I could not find a tutorial on adding scrolling text in this version of shot cut.
There is a picture showing the use of Text: Rich.
I have done with this, added my text, Selected a preset to slide in from the left but nothing appears in the window when it scrolls.
I am missing information obviously. Can someone Point me in the right direction?
Thank you very much!
Peter

See the example here.

If you are still getting problems try posting a screenshot, with the filter selected so we have a better idea of what you are doing. Make sure you capture the whole Shotcut window in the image.
