Why is does interpolation sub-layers works correctly in Action but not in main timeline?

[Panha]

Hi guys,
Please help me with this one. I am trying to do the mouth switch that uses interpolation sub-layers in Layer Setting > Switch. All sub-layers use the same number of points (I copied each layer and did not add any points, just move the already-there points to create different mouth shape). In the Action timeline, the switch works correctly, but when I use that action in the main timeline, it works incorrectly. Please see the video. Thank you.
I use Moho 14.1.

As far as I know, interpolation sub-layes don't work in actions. I want to follow along to see answers.

Oh! I have never known that, I thought it works in the action timeline too. However, I think there is still the effect as in the video I recorded. I had the action of "speaking", and it looks correct in the action, however, when applied the action in the main timeline, some interpolation seem to work except some.

You probably need to insert a copy of the action instead of a reference.

Ok, thank you very much.
