AE 2026 bakes additional alpha stops to match colour stops on Shape Layer/Layer Style gradients - regression from 2024/2025

Steps to reproduce: Create a shape layer or layer style with a gradient → open gradient editor → set colour and alpha stops to different positions (more colour stops than alpha stops) → click OK → re-open the gradient editor

Expected: stops remain at the positions set, with colour and alpha ramps independent. (This was the behaviour in AE 2024 and AE 2025.)

Actual: AE 2026 has inserted additional alpha stops at each colour stop position, forcing the alpha ramp into sync with the colour ramp. The reverse does not occur - extra colour stops are not baked to match alpha stop positions.

Environment: Mac OS, tested AE 2024, 2025, 2026
