Hi Philipp,
at first glance your trigger looks fine, but I would suggest that you add the conditions one by one, so you can verify which of them works in your case.
So maybe just start with the first row and make sure, that the workflow triggers. Then add the next row and try again. Maybe there is really no document that matches your condition or maybe your workflows do not trigger, which means, that you probably have to contact support.
