Max/Min calculations within time range

Hi, I did a dashboard where I pass a list of values and used the value options to get the max and min value of that list, but depending of the time frame I put, the values change, for exemple on a time frame of 24 hours, the highest value should be 12.3, but it’s displayed that the highest value is 8.6, but this value is not in the list. Then if I put the time frame to 12 hours or less, it display the 12.3 as the highest value, and in both times this value exist.

24 hours

12 hours

Value options

Does anyone know why this is happening?
