Incongruity in Self GFlop

Hi, 

I have been having problems interpreting the results for the analysis of one function in my code. I am analysing the roofline results for an application. While doing so I started to check the number of GFLop and the elapsed time in order to compute my own performance and the arithmetic intensity. However when I check the Self GFlop of a non terminal function I have found different results when looking at different views in the Intel Advisor GUI.

In topdown view I obtain a very small number of Self GFlop (< 0.001) for the function interpolate_3D. When I just select that function and click on the Code Analytics tab then the Self GFlop is 3.3544. Are they different metrics? Am I missing something?

I am using Intel Advisor 2018 Update 3.
