move flip box order on mobile

Hi,

I have a series of 5 flip boxes on my homepage under the Key Services section. On desktop, 4 smaller boxes are placed around a larger box that is in the middle. On mobile the larger center box is showing as the 4th stacked box, but I need it to be the third box. here is a screen shot of the desktop view:

Is there a way to fix this, so the larger box is the 3rd box on mobile?

Thanks.
