Illustrator perspective grid

I am having a problem when trying to paste things into the perspective grid. It doesn’t let me move the item and doesn’t move according to the grid


And I also am getting this message, not sure what it means

is there a gradient included? i would try to rasterize the objects first and then add it

expand it first a few times and then try with the perspective arrow

Thank you that worked for one, but the one I rasterized still won’t move… not sure what I am doing wrong

try ungrouping and doing part by part so you can see what’s holding it back
