Almost no journal entries

What I did: I opened the journal log

What happened: almost no entries. Only 4(!!!) for 2018, albeit I file sth every workday

What I expected: that it works

Things that might be helpful to know (Findings version, OS and model, etc):
I used the 'show in finder) button to look at the storde pdf files. It appears that theres one pdf for every month, but each contains only one page with the two or three very frist entries of the month.
