The algorithm does not current support altering existing rasters, and only allows creation of new rasters. The 'add' mode only makes sense when used with updating an existing raster.

i'm using it to create (raster)heatmaps from a large set of tracks (shape polylines),
this future is available in version 2.18

it seems that on QGIS LTR the tool was split in two, one allowing this operation, so it would be better to re-add it also in qgis 3.
