Clean installation of minecraft with fabric mod loader makes "Version button" not displaying at least for me.

Using:

• Fabric 0.9.0+build.204-1.16.1
• Lithium 0.5.1
• Phosphor 0.6.0
• Sodium 0.1.0
• VoxelMap 1.10.4
• ModMenu1.14.5
• clientcommands 2.4.1
• Inventory Profiles 0.4.2.

Tested every mod combo with or without FabricAPI 0.15.1.

Button was displaying properly with latest version of Aristois and same mods (i just copied them).

Java Version: Built in launcher (used)/ JDK 11.0.7

That version button is added by CDAGaming's fork and is not in the official version of multiconnect. Usually you are supposed to rely on multiconnect's smart auto version detector, and if that fails you can press edit server and edit the version of that specific server manually.

As Earth said, The Global Versions button has only ever been available in my fork of multiconnect, otherwise you can find it in the Edit or Direct Connections screen
