Default values changes will not reflect on builds or play mode and the original default will be used, e.g. In Voronoi node, if you manually typed 10 in CellDensity Input field, it will revert back to the default "5" in actual build or in play mode.
Workaround
Don't manually type values in input fields, on above example use FloatConstant with value of 10 and feed it into CellDensity.
