Hi @haribonda !
Note that the Gutenberg plugin is an experimental plugin that introduces new features, and some that are even more edge-case that you can enable from the plugins’ settings.
You are able to use a Column Block from WordPress itself, without needing to activate Gutenberg, and you can test disabling the plugin to see if that helps. I suggest this because you seem to be using a plugin that has blocks that are similar to the WordPress editor’s blocks. I’ve highlighted them in the screenshot here: https://d.pr/i/gKpXLS
You can see that their icon color is different to the native WordPress Block icons.
You can read more about the Column Block and Group Block settings at the links below, as this might help with what you’re working on, by grouping the top level Column Block so that you can add padding, and margins to that Group Block.

Lastly, you can test your plugins by deactivation and reactivation to see which of them is controlling the Column Blocks on the page, then reach out to their support team for more assistance with the layout settings for that Column Block.
Hope this helps!
