iPhone shortcuts app no longer combines photos vertically

I’ve successfully created a new shortcut in the iPhone Shortcuts App so that I can combine photos in my photo gallery. However, once I get to “Combine Images” action, “Horizontally” is the default and there is no longer any way to change how my images are arranged (ie vertically, in a grid, etc.) as was the case previously. I’ve tried a few different things, I’ve Googled the issue, and I’ve scoured Apple Support and Communities for answers and I’m just at a loss. Can someone please help me with this? Thanks!
