Engraving long text on wood

Hi, I watched the tutorial video on Cutting a single project larger than your laser (pass-through version) date Jul 26, 2020, thank you for the video.

I am making a sign on wood material with the area being 600 mm long & 250 mm wide. With the text PROMOTIONAL AREA written on the wood, I was able to get to the point where I made the crosspoint at 9:40 on the video. I selected the text PROMOTIONAL AREA, along with creating a square to split the project. However when I go to cut shapes and try to see if it is split the whole text PROMOTIONAL AREA moves. What would I be doing wrong?
I am using an ORTUR MASTER 2 laser, any advice would be greatly appreciated.

Thank you
