I have check how Party HH works and this may help you :
On this Party skin, when you seat at a table you'll see your screename + Player 1 - Player 2 ....
When your first hand is dealt you'll see on the table All screename.
BUT here is the catch :
- Party will write the 1st hand in the log file with your screename + Player 1 - Player 2 .....
- From the second hand and for all the next one, Party will write All true screenames.
I guess this is what causes HM2 while reading the first hand to switch to 'Session stats'.
Also, maybe a detail, but the 1st hand you play at a table, the one recorded with Player 1 - Player 2 ... is never recorded in HM2. So if you managed to win an entire buyin on this very first hand of the table, you still see a winning of 0€ in your summary or Active session.
My HM2Archive is organized as you described.
You can see on this picture what i described above.

On this screenshot you can also see another problem :
The table name is "évreux".
The name is correctly written in the filename and the hand itself.
But when i replay the hand in HM2, the "é" has disapear. Like if HM2 can't deal with special caracters.
Typically those table won't be refreshed automatically and the HUD is frozen to 0 hand at first. Then you have to stop/start HUD , this will refreshed the HUD to the number of hands you have played. Let say 33 hands. You can play 1 hour and the HUD will show the stats for those 33 hand only until you decide to do another Stop/start HUD.
But even if you don't do stop/start HUD, you still can see the hands in the summary.
I hope this details will help you.
I'll play a few hands today and send my logs.
