My character not showing as linked to guild?


I’m playing on Taiwan servers, in 7.1.5 all my logs uploaded by another member show me correctly as in the guild Violet-TW.

However today after a heroic NH run, all the logs for my character are showing me as being guildless. I checked the guild section here which shows me at the top with a rank of -1. Could this be the issue? I’ve tried to click update but get an error “An error occurred fetching the guild data. Make sure your guild name exactly matches the guild name used in-game.”

I have not left or rejoined the guild at any time so it’s a bit odd.

Here’s a link to me on WCL, i am Vx-warlock:

Hope someone could help me out. Thanks!
