The magnifying glass icon overlaps one of the arrows from the Searchable containers mod. Not sure how you would change it but maybe the players can have an option to change the position of the magnifying glass. or something. The overlapping of the mods allows neither to work as needed.

Use Searchable Containers mod with this Chest tracker mod. Open a chest and look toward the top right where the magnifying glass is supposed to be.

You will see the magnifying glass overlap an arrow in the chest GUI.

Luckily you can still use the Chest tracker mod by pressing "Y" or whatever key is bound
