Description

Operating System

macOS

Installation Method

From source (npm run dev / npm run dev:minimal)

Agent Canvas Version

main

Bug Description

The window to pick the Max Number of Events can go under 0, which is wrong.

However, if I try to save, then an error appears (but not a clear one)

Steps to Reproduce

  1. go to Settings -> Condenser -> Advanced
  2. put a negative number in the Max Number of Events window

Actual Behavior

We can put a negative number in this window

Expected Behavior

It should be somewhat blocked at 0, such that the user cannot select a negative number (in order to prevent errors when saving)
