I installed the latest version of the Gutenberg plugin (5.8.0) in a site with the latest version of WordPress (5.2.1) and Generatepres (2.2.2). I was pleased to note that the Gutenberg plugin added to the columns block the possibility of adjusting the percentage of each column. This is a really useful feature. Unfortunately I also noticed that, when this feature is used, Generatepress displays the columns in a wrong way, however different from what you see in the page editing interface and from what you would expect. I tried this situation even on a completely clean wordpress site without other plugins besides the Gutenberg plugin but I always got the same problem. I tried to use the Gutenberg plugin, again in a completely clean site, with other themes (Twenty Nineteen, Twenty Seventeen, Twenty Sixteen and Astra) and the page was displayed correctly. There seems to be some problem between the Gutenberg plugin and the Generatepress theme. Could you please verify and tell me something about it. The situations is rather frustrating because I have many sites developed with Generatepress.
