P: PS v27.3.1 Curves duplicated in Properties panel display of Curves Adjustment Layer

Hello Adobe Support Team,

After updating to Photoshop v27.3 and v27.3.1, I encountered an issue when using the Curves adjustment.

When adjusting Curves on the composite RGB channel (not individual R, G, or B channels), if I make an additional adjustment afterward, a residual or ghosted image from the previous adjustment appears. If I switch to another layer and then return to the original layer, the residual image disappears. However, if I continue adjusting the Curves, the ghosting issue reappears.

I tested this behavior by downgrading to Photoshop v27.2, and the issue does not occur in that version. The Curves adjustment works as expected in v27.2 without any residual artifacts.

This issue seems to be specific to v27.3 and v27.3.1 and may be related to how Curves adjustments are refreshed or rendered.

Thank you for your time and support. I hope this information is helpful for identifying and resolving the issue.
