Transitions not working

[Lottie5FA3]

I have added six png files and I am copying and pasting a block dissolve transition to the images.  The keyframes are all set to the correct locations.  The first four images transform without an issue, but the last two do not transform.  The settings are the same for all of the images so I don't understand why the last two won't work. 

Here is a video that shows the transitions working on the first four and not on the last two.

Your images appear to be hugely different in size. It might help if you actually pre-composed them to a uniform size or resized them externally. Fitting a 3000+ pixel wide image into what appears to be 1080 square comp will of course scale the image as well as the result of the effect, potentially making it lool like it disappeared completely. Likewise, this would affect how Card Wipe and other effects calculate their parameters to begin with. So for all intents and purposes, start by evening out the sizes of your imagery.

thank you 🙂 I tried deleting the effect and readding it and it worked, but I will keep this advice in mind when exporting from Ai.
