Parallel anim with IX2 doesn’t really work like this 
To begin with, if you want to animate from a state to another, don’t use “With previous” with a delay. You need to set a new step using “After”.
Also, for maintenance and stability, predictability, prefer using different targets for different actions: set the filter anim on the image, and set the scale anim on a container of the image, like a div.
Now, when you have parallel anims that are on a different pace (2sec for the filter and 1 sec + 1 sec for the scale), you kinda need… 2 interactions. And 2 interactions set on different element (again, the filter on the image and the scale on a div).
I get the logic, and if you reproduce this in Keynote using the exact same kind of timeline, it will work. It just doesn’t work on Webflow IX2.
You can remove all the filter anims and your scale anim won’t even work, it’s not because or the parallel, it’s because of the “With previous” with a delay.
