NPCs give Goodbye Dialogue with every interaction

NPC Characters give out goodbye dialogues whenever I’m navigating through their Quests and Conversations in their Interaction Window. Normally an NPC would issue goodbye dialogue when closing their Interaction Window however they keep saying it with every navigation. I performed many advanced CVar Resets, deleted interface, WTF, cache files, all addons etc and reinstalled WoW on 2 brand new PCs and the issue is still there.

I’ve been submitting Bug Reports regarding the issue for over a year now and nothing has changed. I would love to know if there is anything I could possibly do to fix this?

I made a video to demonstrate the issue: https://youtu.be/O5X1gsmfcv8?si=V389Y8X2tfT8YJI0
