LW DS to Ele spec issue

Hello,

I originally had the LW DS specialization and decided to unlearn it, so I went to the DS Trainer and paid 50 gold for the option to remove it. Afterward, I visited the Elemental Trainer to pick up the Elemental specialization. However, the Elemental Trainer is refusing to give me the quest for the Elemental specialization, and now I have no specialization at all.

If switching specializations isn’t possible due to this issue, could I at least get my 50 gold refunded?
