Quests not showing on map bug

Hello,

I have an issue on one of my characters {Crataegus}. Every time I click "M" my quests don't show on the map. I've uploaded a screenshot where you can see the issue.

This issue only happens on one of my characters. I've uploaded a screenshot from my main. The characters are on the same account.

I've already tried clearing the CACHE, WTF and Interface folders. In fact, I deleted and redownloaded the entire client. I am not using any Addons. The issue persists.

First and second image include the view of the affected character - you can see in the right side the current quest log and the empty map.
The third screenshot shows the view of the main character {Aradusa}, on which I do not experience any issues.
