Homepage blocks issue

Hi Jenifer,
For the past few days, I’ve noticed an issue with the blocks on my homepage, even though I haven’t changed anything on my end. I have blocks from both Hello Rosette and Hello Iris, so I’m not sure which one I originally used.
The problem is that a left margin suddenly appeared, leaving a gap on the left side of all blog blocks (see attached).
Could you let me know if any changes were made on your end?
Thank you in anticipation,
Emma
