Set Flipbook Return Value True

One of my Flipbooks just wont work. With a Print Node after the flipbook I can confirm it executes but the animation does not change. While troubleshooting I connected the print node’s “In String” to the Flipbooks “Return Value” and noticed that only this flipbook returns with a value of true while all the others returns with a value of false when executed. With this I then tested and found that every new flipbook that I create regardless of its animation now has this problem. The only thing I can think of is something changed in the “Sprite” that all the flipbooks targets, but I did not change anything in the Sprite.
Is there perhaps a limit to how many flipbooks a character blueprint can have?
Does anyone know why a Flipbook would return a value of true?

Thanks in advance.

OK so after freaking the whole day I finally realized my mistake. Firstly my troubleshooting leaves a lot to be desired. Secondly its about workflow and conflicting commands. Basically I had it so that if there is no movement it would play the idle animation. I created everything for when the character gets killed and set it so that the dying animation plays. The problem was because there was no movement the idle animation would constantly run. For some reason when two animations try to play, the return value of the last flipbook would return with “True”.
