Help with Flats

For a long time flats have plagued me. I have been using APP with only the remove light pollution tool and get VERY good results. This week I decided I was going to get my flats working. Well I have failed so far. My flats are over correcting. In the three images you will see my linear and calibrated lights, and my unstretched flat. The unstreached flat looks like it should work and the result has the data in the correct place, it is just too much. 


Here is a link to the source files, 5 lights, 5 darks, 5 flats, and 5 dark flats.

Any way I can get someone to take a look and see what I am doing wrong?
