Package Japan to UK via France then Belgium?

Ordered a package from Japan, it went through a few places that made sense, then ended up in France for a couple of days (ROISSY CHARLES DE GAULLE CEDEX) but now it's been transferred to Belgium for the last two days? (GRACE-HOLLOGNE).

Just curious as to why it's gone from needing to go an hour North to two hours West? Hopefully it isn't getting further away
