I wrote to Airline Apps and the response is below!
Thanks for your question. The only column that usually does not match your logbook is the PIC column. The reason is that the airlines only want you to report the PIC time that meets the FAR Part 1 definition of PIC.
Therefore, you will usually have more PIC time in your logbook than on your application. This is due to the fact that most pilots log PIC time and Dual received for the same flying time, once qualified in an aircraft. The best way to handle those hours is to just report them as Dual received. This will result in fewer hours PIC than in your logbook and all other times matching.
Please let me know if this helps.
Sincerely,
