@ejazbee,
You are trying to use symbols which have no simulation model associated with them.
Please read the Simulation Tutorial:
https://docs.easyeda.com/en/Simulation/Headings/index.html
Please note that there are currently some problems with some of the simulations in the Tutorial.
Workarounds are described here:

Brand new interactions and interfaces.
Smooth support for design sizes of over 3W
devices or 10W pads.
More rigorous design constraints, more
standardized processes
For enterprises, more professional users.
Easy to use and quick to get started.
The process supports design scales of 300
devices or 1000 pads.
Supports simple circuit simulation.
For students, teachers, creators.
