Hide custom advancement in the minecraft namespace

Hi there, I did the change in pack mcmeta to hide all vanilla advancements of Minecraft for my minigames server. The problem is i have a custom one in the minecraft namespace, that players grab at their first time in the lobby and absolutly need to keep this way. The block filter doesn't apply to this one, and i don't know why cauz the path is still minecraft - advancements/.*, no ? Mcmeta : { "pack": { "pack_format": 61,"description": "Krogames Datapack" }, "filter": { "block": [{ "namespace":"minecraft","path":"advancement/.*" } ] } }
