On top of the door style, that pattern on the door (looks almost like a heart) is one I had on my first cage years ago, and when my bird moved out into another cage and I put a different bird in, she later got her beak stuck on the curled part of the design - luckily I was home and freed her immediately but it definitely spooked me and her! Those funky wiggle patterns appear on many bird cage doors.
edit; If you can only find cages with guillotine doors, you could tie strap them closed, and if the main door is guillotine, clip it closed with a little SS keyring clip. It´s just important they are secured in some way or another
