Mouse over animation added to image - can't be removed

I have 9 columns with thumbnail images. Each image has under interactions “navigate to URL”. After adding the images and interactions, i decided to add a mouse over animation (pulse). I selected each image and added the animation.

After deselecting (clicking away) from an image, and then re-selecting the image the animation which I just added no longer shows up in the animations section on the right. But if I preview the page in my browser, the animation is still present and working.

So now I am confronted by the problem: I can’t remove the animations. They are not showing as applied in the animations section on the right. So according to Blocs, they are already removed (which I never did - Blocs just chose to remove them on its own :wink:
