Hello @Jok
Welcome to the forum of PP. 
There are two PDF documents at Degiro.
One is the “account”, here bookings and DIvidenden are recorded.
In the “transaction” all purchases and sales are recorded.
If this does not work correctly, then please create a PDF debug.
How this works, you can see best in the video tutorial.
