Half Orc Paladin having targeting issues

[Macabreus]

I have a campaign i am running that during combat the half orc paladin when she rolls for attack, damage etc randomly targets party members or enemies despite the fact she only has the enemy targeted. This results in her making an attack roll against a friendly or applying the damage to a random PC or NPC. I have tried:
-Removing from the tracker and replacing
-Creating an entirely new PC from scratch using the 5e PHB
-waiting for updates
-Using a different weapon to attack
-Making sure her setting are the same
-Reinstalling the software on a new computer

The issue is still occurring but only with her character. Everyone else seems fine. Anyone else seeing a problem with the Paladin? not sure how to fix this. Right now she is just manually dragging onto each character instead.

Does it still happen when that player plays a different character?

Oh and as ever are you using any extensions? And does the problem persist in a new campaign without extensions.

User error?

I dont believe it is user error. I have tried it myself from her computer.

I have not tried a different type of character, or having her control another, but i did create an entirely new character and deleted her old one using the 5E PHB dragging and dropping the class for levels, the same way we have created every other character. That still did not work. Right now I have the ultimate license and I am using Princes of the Apocalypse. I thought it may be the older laptop she had at first too, but now she has a new Asus laptop and fantasy grounds install.
I will try giving her control of someone else's PC and see if it still occurs.
Then, I will try recreating the same paladin in another fake campaign and see if it still occurs. Ill let you know what I find.

We tried with her controlling another character, using different weapons, etc. it seemed to be fixed for a short time, but started changing again after she put "magic weapon" on herself. We then tried putting magic weapon on another character but they did not experience the same problems

Please provide screenshots of the issue - showing the combat tracker with any effects and targeting active, the character sheet with the action/s that are being rolled and the chat window showing the results of these actions. This will give us a chance to help track down what the issue is.

Might it be a "use Magic Device" fail issue, leading to random targeting. Does she ever damage herself?
