P: PS 28.0 MUI Properties Panel: Adjustment Layer sliders snap back to default value – Ps 2027

Environment:

• Application: Adobe Photoshop 2027
• Platform: macOS

Summary:
When adjusting settings for certain Adjustment Layers via the Properties panel, moving a slider updates the value, but clicking anywhere inside the panel or interacting with a second slider causes the previously adjusted slider to visually snap back to its default value. Reopening the panel shows that the custom value was retained internally. Typing numeric values directly into the input field works normally without resetting.
Affected Adjustment Layers:

• Black & White
• Channel Mixer
• Photo Filter
• Selective Color

Steps to Reproduce:

1. Open any image in Photoshop 2027 on macOS.
2. Add an Adjustment Layer (e.g., Black & White or Selective Color).
3. In the Properties panel, drag any slider to a new value.
4. Click anywhere inside the Properties panel, or begin dragging a different slider.

Expected Result:
The adjusted slider remains at the newly set position, and the numeric field reflects the change.
Actual Result:
The slider instantly snaps back to its default/original value visually. However, closing and reopening the panel reveals that the entered value was actually saved.
Workaround / Notes:

• Manually typing a number into the input box next to the slider works properly and does not trigger the snap-back behavior.
  
  The issue is isolated to slider dragging / UI focus changes in the Properties panel.
