digital stopwatch circuit not working/running smoothly

I made the following Digital stopwatch circuit  using IC 7490, 7448 and cathode seven segment display on multisim and the transition between 2 and 3 and some other states isnt  smooth or is getting stuck. What modifications can be done to run this circuit perfectly ?

Hi there,

 

In Multisim go to Simulate>>Mixed-Mode Simulation Settings and select Use Real pin models. This mode requires power and digital ground which you already have in the schematic.
