Realms disable global resource pack issue

Recently I've been using a combination of resource packs to make the textures look how the game looked back before 1.14.

We're making factions so I decided to put a banner on my shield but I realised that it was all low quality once I had put it on the shield so I got a resource pack to fix that

I put it on the realm so people could download the RP to see the shields normally. However since doing that, my friends RP & now my RP don't work on my Realm.
