iPoker hand import after "Update local information"

Hi.
4-tabled a short session last night at Titan testing the PT3 I just installed earlier; anyway my computer crashed during the session (had PT3 autoimporting and hud running) [the crash wasn't because of the PT3 I'm pretty sure, and it is not the issue]. As I got the system running again I went and ended the session without starting PT3 at that time; obviously iPoker nicely brings one back to the active tables. I looked "my account\cash table history" on the Titan client to check the session hand histories; and obviously had to "Update local information" because of the crash (as session totals wouldn't display correctly othewise), I counted I had played 132 hands. Then I restarted the PT3 and tried autoimporting rest of the hands; the import window showed some hands imported and some duplicates (can't remember exact numbers). Then I went to see the stats, but theres only 62 hands of that current level in database!!! So I moved the hand history files back to Titans history folder and looked at "my account\cash table history" and even updated local information again. Next I autoimport again to PT3 and now it shows 132 duplicates and no new hands but still theres only 62 hands on that level on player summary!!!
So where did those other hands go? Does that "Update local information" somewhat corrupt the handhistories so that they can't no longer be read to PT (same issue with PT2?). How can there be 132 duplicates when theres only 62 hands on database?
