Slides per view set to auto has a bug

I have been trying to use the auto setting so I can show a certain number of slides, plus a little bit of the next slide. I set each view to be auto, and assign a percentage. This looks ok when added to my page, but as soon as I publish it, the percentage all default to 40%, and thereafter I can’t change them.

Hello @jacques! Could you please share a read-only link? I’ll take a look
