Photospace not working

I installed and activated photospace and uploaded 27 images for a gallery on a page and the gallery only displays 4 images.

I tried deleting the plug in and then re-installing but it still doesn’t work.

This is the gallery my boss wants but I simply can’t make it work.

Any help would be greatly appreciated!
