Unable to add random intercept (Intercept | Dyad ID) in Mixed Model — arrow and drag not working (Mac)

[Deepti]

Hi everyone,

I’m trying to compute ICC using the Mixed Model in jamovi, but I’m running into an issue when specifying random effects.

What I am trying to do:

• Dependent Variable: MeanSat
  
  Cluster variable: Dyad ID
  
  Random effect: Intercept (Dyad ID)

Issue:

• I am able to create the component “Intercept | Dyad ID” in the Components box, but:
  
  Clicking the arrow (→) does not move it to the Random Coefficients box
  
  Drag-and-drop also does not work
  
  The right panel shows: “Select at least one term in Random Effects”

What I have already tried:

• Ensured the dependent variable is added
  
  Clicking (not dragging) before using the arrow
  
  Resizing the window
  
  Restarting jamovi
  
  Recreating the analysis from scratch

System details:

OS: macOS

jamovi version: 2.6.45

This seems like a UI issue rather than a setup problem. Has anyone encountered this, or is there a workaround to correctly specify the random intercept?

Thanks in advance for your help!
