When using the Minimum and Maximum values on the Structure Set page they will reset their values.
This is a known bug, and will be fixed in the next update.
For now, what you can do is Lock the element files and modify the structure_set file by hand.
Min = separation
Max = spacing
// Example for Min=500 and Max=1000
"separation": 500,
"spacing": 1000
// Values can not exceed 4096 (inclusive), but separation needs to be below the value of spacing.
// Example:
"separation": 0 ~ 4095,
"spacing": 1 ~ 4096
