Talk to the author of the addon, he manually adds special skills and may be able to help here to remove the skill on the backbar once it was used with the 2nd usage AND the morph of the teleport is given at your toon.
I know he had worked on some skills "manually" to fix (non-given/wrong/missleading) API stuff.
btw: ZOs vanilla UI tracking of skills is kina inspired by Action Duration Reminder
And it lacks a lot of features the addon got + special treatment the addon does since years for the special skills.
