Hi there, I found this little one here and I don’t think it is intended… 
The grid editor of a repeater is not displayed unless you change some settings.
Was able to reproduce it!
Cheers

Hello @T-low,
Thanks for the report.
We don’t set a default display on the Repeater block, which in this case would explain why the Grid Editor doesn’t appear. Setting your display to grid should show the Grid Editor.
However, toggling the Slider property off does set the display to grid, which might be something we should review.
I’ll be moving this to General as not a bug as such, but definitely something we will be looking into.
Thanks for bringing it up.
Cheers,
