Choose instance based on position: what am I doing wrong?

An example of the idea here:

You drag the Dmg Enchantment (the text sprite), drop it on the Enchant Slot next to the bow (a Equipment) and it sets the Dmg_Enchants variable for the bow.

The problem:

It changes the same variable for the gloves as well.

I tried with pick nearest too and I had the same problem.

I also tried other syntaxes for comparing X, same thing.

After some time away from the project I had an epiphany and made it with other method, and it's now working. But if anyone could still explain what I did wrong there it would be of great help. Thanks!

It must be something off with text hotspot or origin/image point.
