Sims age is going backwards

I'm having an issue where my teen sims, instead of aging so for example 5 days left to age up, 4 days left, 3 days left... It's going backwards so 5 days left to age up, 6 days, 7 days (not the actual age numbers but i forgot the number and it's an example)

yes aging is turned on, and they have a slight green bar on aging, i do use custom ages with mccc but it persists without that though i do have other mods but i'm not sure which one would be effecting the game this way.

it does this for both normal and long lifespan i've not yet tried short.
