When I check on this it would appear that the block wasn't set to be full width.
Given that your other site is working I would recommend going through and checking the settings of the column block to see if it is setup the same as the test site with the update.
I managed to restore the full width by setting it back in the container block but i'm not sure what other setting is missing.
I was able to replicate the issue, however it may not be the latest version that is causing the issue as there were many changes to our blocks plugin from version 1.3.2 that you have to version 1.5.2
As well as these css isn't coming from Toolset it is actually coming from the Astra theme. The most we can do is to overwrite them to resolve the issue.
You can add this to the CSS section of you content template.
