Comment 3 for bug 1925349

Thanks for your report!

I think the root cause is old (March 2019) translation templates, i.e. the original string has been changed since then. I just committed an update:

At next upload of the ubiquity-slideshow-ubuntu package, new and modified strings will become available for translation.

So probably this will improve in Ubuntu 21.10. Maybe in coming 20.04 point releases too.
