After updating to AE24 I started to have two problems with copy/pasting effects in the Effect Controls panel:
1. Copy/paste within a single layer no longer works ā when I need to stack the same effect on a layer, if I copy effect it in the Effect Controls panel using Cmd+C and try to paste it on the same layer using Cmd+V it does not work anymore. For this one there's a workaround, as Cmd+D to Duplicate still works, but there's another problem, probably connected to it, which is...
2. Copy/pasting effect from one layer to another layer that already has the same type of effect just overrides it. Say, if you have Numbers effect on Layer 1, copy it using Cmd+C in the Effect Controls panel, select Layer 2 which already has same Numbers effect applied with different params, and paste effect using Cmd+V ā the parameters of existing effect get overriden with parameters of the pasted effect, while the expected result (and as it always used to work) ā the pasted effect should become stacked as a separate instance in the Effect Controls panel. To workaround this bug I need to duplicate existing effect, then paste the copied one to actually override the second effect.
Obviously a bug that breaks expected workflow that always used to work in AE.
