Problems with generating AC waves

Hi, I was trying to make a full bridge rectifier but I noticed that my AC source has a problem to even generate a proper sine wave. The frequency of AC generator set in the diagram below is 50 Hz but there is no response from the scope . However, if I were to try 10 Hz , there will be a sine wave. Please send help!!

Your circuit works fine on my end, could you please upload your model?

This circuit works fine on my computer. Without a model is hard to give any advice. First thing I would double check is that 'Peak amplitude' is not set to 0.
