Cannot assign MonoBehaviour script to AddMonoBehavioursModifierType array in inspector

Question

Like the title implies, i cannot assign a MonoBehaviour to the Array in the inspector window for AddMonoBehavioursModifiersType script. I get an error message saying "Selected object is not a MonoBehaviour type!".

This should be straight forward, as i've seen others do it without problems (youtube tutorial by mapbox). What is the cause?

• Unity version: 2020.3.1f1 LTS
  • Scripting Runtime Version: .NET 2.0
  • Scripting Backend: Mono
  • Api Compatibility Level: .NET 2.0
• Mapbox SDK version: 2.1.1
• The platform you're building to: PC, Mac and Linux standalone
• A description of what you're trying to do: Assign MonoBehaviour script to each rendered gameobject of Map Prefab
• Steps to recreate the bug if appropriate:

1. Create a C# script (right click editor > create > C# Script)
2. create a Mapbox MonoBehaviour Modifier (right click editor > create > mapbox > modifiers > add MonoBehaviours Modifier).
3. Click + icon in inspector window for newly created Mapbox Monobehaviour Modifier and assign the newly created C# Script to the Array of name types. Here i get the error message:

Selected object is not a MonoBehaviour type!

Edit: Solution: After restarting the computer and Unity, it worked by itself.
