First impression is that the software isn't reading it properly - or the sensors are stuck. Even then tho, I would doubt they'd stick at the same temps.
Out of all the quads I got at home, it's extremely, extremely, rare for all 4 to be the same temp. Often 2 might, 3 very very rarely.
It could ofc have been a co-incidental screenshot. If so, buy a lottery ticket imo.
