I believe you are using the callout module there. The reason that is happening is the length of text content in that one callout module. It is shorter than the others. You would need to add some bottom padding to that specific callout module those 3 in a separate row and tighten up the spacing. You could even try doing an extra return in the text editor of that one callout module.
I don’t understand unfortunately, Rafael. Did you give my suggestion above a shot? I’m also not sure of what you mean in your second question, I don’t see a lower scroll bar?
As mentioned above, the callouts were all in the same row. One way to accomplish what you needed was the option of adding each 3 callout modules to their own row as opposed to all in one row. Also, adding a return in the callout module text area above the one that was misaligned was an option. I went with the second solution and you should be good to go there.
I can’t see the screenshot of the events page for some reason, can you send a new one?
I am checking the site and it seems the Callout Modules are aligned? Also, I’m not experiencing that scroll bar problem from my end as well. It could be a browser issue or browser cache? Try doing a force refresh on the site. Screenshot below on how I’m seeing the Homepage. http://imgur.com/I0pn0sP
Regarding the templates, it has been a part of the plugin for a while. The new update just brings the Templates to the admin menu. If you want, you can disable that under Settings > Page Builder > Templates. But it will still be available on the Page Builder menu under Templates. You can just delete those layout templates and it won’t affect the pages using them but once you do, you won’t be able to get them back. You might want to export them before doing so. More of that here.
