Copying Settings to paste but when I try to paste to 500+ photos it only pastes the setting on one photo.

What am I doing wrong, currently im trying to copy the aspect ratio to ORIGINAL and paste those to all photos, but it only pastes it to one of the 500 photos I have selected... this is very annoying

Are you in Library's grid? It's best to be, and then just check in the Metadata panel that it's set to Selected Photos, not Target Photo.

Or are you in Develop, selecting the 500 in the filmstrip? In that case, is AutoSync enabled? Should be.
