Hello @JimTanyaP ,
It looks like this might be a newer issue specifically affecting 3ge versions of the 3-column layout block. Our T2 team is documenting the issue, however, since 3ge is being slowly phased out in favor of the CPE email builder released back in 2020, they're not guaranteeing the issue will be resolved.
With that said, we did notice that the issue doesn't affect 3-column setups if manually created - i.e. dragging over 3 separate image/text blocks to place side-by-side in a single row. Additionally, the issue doesn't present itself in the CPE version of the 3-column layout block. Going forward, if you wish to just copy your last sent email, I'd advise deleting the affect layout blocks, and constructing your own multi-column setup. Otherwise, you can rebuild your template using the CPE, which you may end up having to do anyway in the future as 3ge continues to be phased out over the next few years and enters retirement waves.
