What does the blue circle depict in the Create Object block?

What does this blue circle mean?

Thanks

I’m pretty sure this is just a new interface bug. You can ignore it.

I’ve also – for a long time – seen a bug where if you are entering a number or sometimes text in a field in the Blocks tab and you click Preview before you complete the entry, it shows that number/text over the preview. It doesn’t affect the functionality but it’s weird.
