"Thanks for subscribing" line shifting the original design out of view?

[myhope]

Client has found an error on the mailing list, I can't figure out how to fix it. I just want the "thanks for subscribing" line to appear underneath the form. But the hidden message shifts the whole design up?! When I tweak on Google inspect it kinda does it, but as soon as I transfer to VSC and save it reverts back to being cropped
