What does 3D max value in CST mean?

I ran some simulation and computed the E field value at 1GHz in CST MWS. I as I looked at the 3D plot it showed 3D max value 68.52 at -1 0 0 photo attached. I exported the the ASCII file for the plot data and got the value at -1 0 0 as follows

16.9447 3.14621e-007 6.43272e-007 0.289293 3.87549e-7 8.43441 e-8

This doesnot look anything like 68.52 mentioned. Any ideas as to why this is happening?
