Input Data entry affects entrance animations

Hello

I have a slide with buttons that reveal layers. When you click a button to reveal a layer, the layer has an entrance animation on 'fly-in'. 

These all work fine apart from one layer that has an 'Input > Data Entry' field on there. This seems to stop my entrance animation from working - I know this because if I delete the data entry field, the entrance animation works.

Does anyone know what I need to do to enable the entrance animation on the layer to work when a data entry field is on that layer?

Thanks, Nisha
