changes not saved with Gutenberg

Hi Paulo! Love this plugin. I just noticed, it seems like with Gutenberg that the code is not saved. If I have Gutenberg enabled, I can scroll down, add CSS to the page, but when I save (with Gutenberg active), it does not save, and when I scroll back down to view CSS, my saved CSS is gone. I was able to deactivate Gutenberg, add the CSS and then reactivate Gutenberg and it seems like the CSS is there but to actually add code in Gutenberg, appears to be a saving problem. NBD just thought I would mention it. Thanks again this makes life so much easier!
