Animation "Amount" works when set manually, not when set by formula

I have a 'Complex Animation' set to move an object by 'Y Offset' with a value of '-300' and the animation works normally when the 'Amount' is set to '100'. If I manually set the 'Amount' to 50, then the object only moves '-150' when the animation plays, as expected.

When the 'Amount' is set by a variable or formula, the correct value is shown in the 'Text Preview' but the last-used manual value is shown in the animation editor. This prevents the animation from running the desired 'Amount'.


This should be fixed on 3.26 (last beta) please check
