Cannot select individual elements in Canvas

Whenever I click a View element in the Canvas, it just highlights the simulator bezels in blue and says "Multiple Selection"

I've scoured the internet but can't seem to find anything about this. In the newer sub-view files I've created, clicking elements individually works as normal. I've checked just about every setting and there's no difference between those and my main ContentView where I'm experiencing the problem

Editor > Canvas > Show Selection IS enabled

I was trying to ignore it for a while but it's hard trying to tweak alignment of elements without being able to see their frames visually

Xcode version: 13.4.1

Is it SwiftUI preview ? Please show screen before attempting to select and tell which element you try to select. Also show associated code.

Turned out to be my fault. I cut each View element individually until the borders returned to find the problem. One of my padding modifiers uses a variable and I'm guessing the preview breaks when it doesn't explicitly get a Double there. Fixed it by just changing padding(.bottom, myVariable) to padding(.bottom, 0.0 + myVariable)
