I see what you mean now. However it’s only happening when using “Cross Fade”. The other animation types, like slide or fade over, it works fine.
The Slider component is a native element and there is hard coded functionality on the back end that we can’t adjust. I would simply use another animation type to keep your project moving. These components are not full-proof, especially when combined with animations like you have for the text. Native components can sometimes conflict with animations.
