Target issue

[Maxuli]

~~Solved~~ Changed the keybind to another button and then changed it back. Somehow that worked.

Target nearest enemy doesn't work on one of my computers.
When I play on laptop it works perfectly in PvE and PvP.
On my other computer it doesn't work at all, it keeps targeting random people far back in the enemy swarm.

As far as I can find my settings on the computers are the same. What have I missed?

Keybind > Targeting
Target nearest enemy: Tab
Cycle through enemies nearest to farthest: shift+tab

Character configuration > Target
Target Type: Target closest enemies: Type 2: Cone

Target settings:
O - Automatically lock on target when initiation auto attack
O - Automatically face target when using action
X - Disable targeting of pets and minions when in battle
O - Switch target circle to target select
