Intensity FX bug?

when selecting any fixtures and choosing a pre defined intensity effect ( chase fade smooth ect) a hard value of 50 percent is applied to the intensity. shouldn't the base of these effects be 0 by default?


if i open any of these stock effects i see "All types with an effect " with an fx symbal and 50% in the intensity column. this has been bugging me for at least the last 2 software versions... anyone know f its a bug of if its something that has been introduced
