Those settings in the menu are the new default settings for single player instead of having everything set at 1x, the fastest maturing dinos take just over 90 mins, cuddle interval is 2 hours but only dodos, lystros & Archaeopteryx can't be imprinted, everything else can, if you have single player settinga enable as well then it stacks on top of those and makes them ridiculously fast
The best thing to do is uncheck single player settings as it completely messes up breeding, if the game is too hard then just boost the dino add per level multipliers and maybe increase baby imprint stat scale so you get a bigger reward for imprinting
