The bug

Commands that run from a scheduled function are listed under "weather" in profile results obtained with /debug start. In contrary, commands that run from the tick.json function tag are listed under "commandFunctions" > "minecraft:tick". Adding new "scheduledFunction" > "<function name>" profile path to match this behavior should be a simple fix.

Reproduction steps

1. Create a new world with default generation
2. Put the attached datapack MC-226038.zip in the datapacks folder of the world
3. Reopen the world or run /reload
4. Press F3 + L to start profiling
5. While still profiling, execute

   /schedule function mc-226038:test 1s append
   

6. Once profiling has finished inspect the report, or upload it to https://misode.github.io/report/
   The commands of the function are listed under weather
