Short lifespan problem

Hii, okay so my problem is that when i play on short lifespan, it feels like its super long, because i’m playing sims legacy thing, anyway, am i the only one with this problem because my oldest one whome i played since he was born on short span and now he is dead, but before he died i checked for how long he lived and it says 105 days, so i went googling and it says that short life span should be around 48 days, so I’m confused because i know i had short life span whole time turned on because i was checking constantly. So is it okay or do i have some glich?? Oh and i don’t have any mods on so im confused???
