Genuine GW bug or visual only?

Platform, device version and operating system:
Nintendo Switch

What you were expecting to happen, and what actually happened:
We were expecting to be fighting in B3 this week, we are actually against a guild showing in B3 but for some reason we are at the bottom of B2 despite being the only scoring guild there at the moment?

How often does this happen? When did it begin happening?
First time it’s happened to my guild, although the last time we were in B3 none of the guilds in B2 had a score at any point in the week either.

Steps to make it happen again
Just go to GW menu & ranking.

Also, my guildies probably won’t thank me for this (but it’s unfair if it pushes others rewards down) but we are currently looking at rewards for rank 10+ - if we are meant to be in B3 we should be looking at rewards for rank 20+
