Since firmware 4.8.xxxxx it is no longer sufficient to simply copy your custom dictionaries into the .kobo\dict directory. Now you will also need to make sure there is an entry for each dictionary in your Kobo SQLite database .kobo\KoboReader.sqlite.

In your case, both Dutch and German are already Kobo-supported languages so there isn't a lot extra you will need to do, but you will need to find and use an SQLite editor utility. I use the free SQLiteSpy on Windows 10, but there are others.

Whichever utility you choose you will need to find the appropriate way to open the database file, then run an SQL command to update the Dictionary table. It should look something like this:
Code:
INSERT INTO "Dictionary" VALUES('-nl-de','Nederlands - Deutsch','true',nnnnnn,'','true');
but replace nnnnnn with the exact size (in bytes) of your dicthtml-nl-de.zip file.

ETA:
  • I'm not sure, but you may need to do a full power recycle after doing the database update.
  • If you're not familiar using SQL you may want to take a copy of the database to practice on.
