WordBee data - Jobs table

I have a question regarding the data that it is available to get from WordBee as we are aiming to understand our activity in the past as far as it is possible.

Thus, I managed to get 4 tables: Projects, Persons, Jobs, Companies.

In particular, I am interested in the Jobs table as I can get significantly less number of rows for it than the number of rows that I can see in the UI, i.e. 1244 against 234540.

As for the other tables, I can get approximately the same amount of data as I can see in the UI.
