Should reflux still be full of fluid?

[amlsml]

Running 2 of my sugar wash lowliness. Total of 5.5 gallons of 100 proof. I added 2 gallons of water and put int my mile hi 8 gallon reflux still. I had 2 coils of copper and rings in the column and had the reflux condenser between 2 glass gin baskets that were empty. I added the second so my parrot would fit. Ran slowly until the boiler pot at at 180 degrees, the entire column was filled with fluid , it would rise above the reflux condenser then spit out at least 500 ml of 190 proof . I shut it down because I can't believe that the entire column should be filed with alcohol? Is my still too full, is this correct?
