Bug/Issue Can't get my profession/skill

Hello,
I'm having trouble with a profession that I've received when getting the level 5 of fishing. When the notice of skill appear to me I minimized the screen just to see a notification on my desktop, I returned and the notice of choosing the skill just disappeared. I tried fishing again the next day, slept, and the next day too, but it doesn't appear more to me. I'll have to wait till achieve the next level to see if it shows up one more time?
