Complementary MOSFET symbol in Multisim(Electronics Workbench)
Sure does look wrong.

Here is the actual datasheet for the Fairchild NDS8852H:

Here is a link to a spice model.  Perhaps it could be manually edited into Multisim.

If not editable you might copy the component, make the corrections, then save it to a similar named part.

If you report it to NI be sure to include the MultiSim version # your using.  Per the NI web site the latest version seems to be lucky 13.
