Adding new blocks to pagebuilder, multiple carousel problem

I wish to add new blocks to “available blocks” of page builder by duplicating some blocks and customizing them independently.

In example, I wish to have 2 versions of text blocks, each should have a different background color, and I wish to use them in pagebuilder.

My second question is about carousels. Right now when I add 2 carousels on a single page, the 2nd one doesn’t work and it’s arrow controls slide the 1st carousel instead of itself. Is there a way to workaround this?

Thanks for the great theme.
