This was mentioned in a forum post from 2017, looks like it’s still happening. One of the seat positions consistently displays it’s name 1 seat to the left. We’ve tried deleting and rebuilding the zones, didn’t fix the issue. If another player sits at the position to the left (that has the incorrect name), their names overlay each other.
Here’s the forum post

Also, the table we are testing with is Hexagonal, not Octagonal. Apologies. (Both are specifically mentioned in the form post)
