Why is my gear randomly downgrading?

Logged out last night with full 578+ gear, logged back in this morning and one of my rings dropped to 128 and a trinket to 134

Please fix this before it becomes a bigger problem, Blizzard

Edit: So, this seems to be a visual bug. I noticed when I replaced one of these downgraded items and my health went down despite “upgrading” by about 9k stamina. I logged out and back in and the items fixed themselves
