Error when trying to open a model in MATLAB r2018a

When I try to open the following example model: sf_car . I get the following error: "Error using findExample (line 35) Example "AutomaticTransmissionWithActiveStateDataExample" not found in "C:\Program Files\MATLAB\R2018a\examples\stateflow\examples.xml".

Can anyone help me in solving this ?

Thanks,
