Figures in Sequences random behaviour

I'm finding my main Figure in a sequence changes randomly as I am creating a sequence of steps. As an example;

1. Create a figure and set the visibility of parts on the sBOM and click 'Use current View'
2. Go to animation tab, start creating a Sequence
3. On the first step, fade most components out while recording so there is a key frame
4. Continue to add components on subsequent steps
5. At some point the main Figure either explodes components or starts hiding components
6. Try and set the main Figure to have correct parts visible
7. Click onto any other part of the sequence and return, parts are still invisible

I'm finding this behaviour to be a bit erratic between parts hiding and parts being translated to random locations. The biggest frustration is with translation as when I try and edit the part translations in the Figure, it propagates through the sequences in an undesirable way. As it stands, all my sequences start with a random image that is not representative of the subsequent sequence steps so it's quite frustrating! 

I am using Creo Illustrate 9.0 Essentials
