Been testing the height ranges some more, and found some discrepancies between Optifine's and Skyboxify's format.
These are examples that work with Optifine, but not with Skyboxify:
heights=(5)-(10) - positive values in brackets
heights=-10-20 - negative min. value, positive max. value
heights=-10-(-20) - negative values
heights=(-10)-(-20) - negative values in brackets
PS.
This is an example that doesn't work with Optifine:
heights=-10--20 - negative values without brackets
