Why did my natal chart change?

I first did my chart when I was first interested in astrology, which was a few years ago (it was done on cafeastrology.) It said I was an Aries sun, Leo moon, and Aquarius rising. Seeing my chart was what made me a believer; because the placements were so accurate.

Fast forward some years later. I kept the old screenshot, but was doing my chart on another device. It said I was an Aries sun, cancer moon, and Pisces rising... which isn’t accurate at all. On top of that, my houses changed. On sites other than Cafeastrology, my moon sign remains cancer, but it goes back to being an Aquarius rising. What’s the deal?

I know for sure I entered the corrected birth info the first time I did my chart, and I am not the only person this has happened to. I did a chart for a friend in September, one who is a Leo with a Cap moon and Sag rising. Now, her chart is a Sag moon and Scorpio rising. However, we’re the only people I know of whose moon signs have changed; the few others I’ve met that have experienced this have only had it happened to their rising.
