Click GUI not working

[PotatoSlayer56]

Inertia Utility Mod version:3.1.3 Minecraft version:1.12.2 Operating system:Windows Optifine/Other mods:N/A Launcher:MultiMC

What's the bug: The click GUI does not work, I can move the categories around but cannot open them.

Crash-report(if applicable)(located in .minecraft/latest.log): N/A

Final checklist:

• [x] I know how to properly use check boxes.
• [x] I have tried to reproduce this bug after removing all other mods, including Optifine or Sodium.
• [x] I have attemped to reproduce this bug using the latest available release of Inertia.

Edit: Fixed Inertia version from 3.13 to 3.1.3
