Duty Finder timer until allowed to reque keeps resetting

[Vespar]

I left an Ampador Keep Duty Finder party 20-30mins in, as we were just wiping constantly, I was given the 15minute wait timer until I could access Duty Finder again. I spent 13 minutes in Uldah near the adventurer's guild and decided to move to the next zone to check the market boards. When I zoned into the new area the duty finder wait timer reset from 2 minutes back to 14minutes and I had to wait another 14 minutes for it to finally allow me to queue for a dungeon again.

Now again,a few days later, I had to leave a party mid-run and I experience the EXACT same issue. The timer started @ 15minutes, I sat in the zone for 3 minutes then chnaged areas. After zoning into the new area the timer had reset to 15 minutes again. Why is the 15m wait timer resetting upon zoning?
I'm assuming this a bug so I'm posting it here.

Update: Okay so right after my timer ENDED I switched jobs, and teleported to Uldah from North Shroud. Upon entering Uldah, My timer which was 0m to reque had bumped up to 8minutes again.

Update #2 I tested this by running from Uldah - Steps of Thal with Timer @ 4minutes to Uldah - Steps of nald. When I zoned in my timer was now 5minutes. Screenshots to show this.
