Thank you to report that. However, Toolset Blocks is a paid tool and I do not have that to test it out.
What exactly the issue? Can you share some screenshots and error here?

Well, I might not be more helpful with this unless I am able to test this out myself.
But the thing is this plugin is not manipulating any block content, we are just adding a CSS class and add some additional attributes for the stylings.
This is also strange that only the paragraph block is being affected, as we are applying everything similar to all core blocks.
Maybe the Toolset guys can better debug this as they may test it with both plugins. Let me know what they update you. I will leave this issue open for now.
