Auto Update does not work

[Zacrain]

Auto updating include guards when renaming a header does not work for me.

My settings, which deviate from default:

Include Guard: Macro Type → Filename
Remove Extension → disabled

If I call the update myself using the command palette, it works. It just doesn't do anything automatically, when I rename a header via F2 or context menu.

Restarting or reloading VSCode does not help.
