Hello
I work for the traffic department of the city, so I know the situation quite well. The one-way mapping is correct. You can check by comparing it with the traffic sign data available here: https://www.geopunt.be/shared/5a1360ad-883b-40f4-bf3a-6ce5d0d6ee0a.
I do notice that the cycle path on the north side of the road is partially missing (it was built later than the one on the south side). You can go add that if you like.
Greetings
