"Convert to Grayscale" doesn't work

[Jonn3y]

Describe the bug The action "Convert to Grayscale" does not do anything. It is added in the History but Lightroom Classic is not toggeling between Color/Black & White. Seems like the Camera Profile is not changed to "Adobe Monochrome"

When using the Lightroom UI "Threatment: Color | Black & White" it works.

Expected behavior Action toggles between Color and Black & White and Camera Profile is changed to "Adobe Monochrome"

System(please complete the following information):

• OS: [Windows 11 - Version 10.0.22000]
• Lightroom version: Lightroom Classic 11.5 [Build 202208080927-8a575c91]
• MIDI2LR version: 5.4.0
