Retainers: So many text boxes!

[LuSnow]

Hello Cuties

I have a little trouble with the retainers of my latest alt (black mage).

2 of them got level 30. Since then, every times I talk to them, I get an additional black text window to inform that I can change job (like for example, bard for archer).

Problem: I can't get rid of the notification! Every single time I talk to them, I get it.

My questions: Why is it coming only for the retainers of my newest alt (don't have that by the retainers of my main and my other alt, although I didn't change their job)? Is it new? How can I turn it off?

Thanks in advance
