This warning is generated when there is more than one parameter block for the same parameter. In this case, Ultra Fractal only uses the last parameter block, so you can safely remove earlier parameter blocks for the parameter to fix the warning.
Example of wrong code:
default:
param MyParam
caption = "This is totally ignored"
endparam
param MyParam ; Warning generated here.
caption = "My Parameter"
endparam
Example of fixed code:
default:
param MyParam
caption = "My Parameter"
endparam
