I've managed to work out what the problem was, it's not Tyflow... I am rendering it out using Chaos Vantage over Live-Link. From the Live-Link settings, I enabled the below setting and got the correct result. Might be useful to know if anyone else experiences a similar issue.
**Enable Object Render State** – When enabled, uses Render states/counts/iterations/modes instead of their viewport representation. Anima 4D assets require this option to be enabled to be rendered properly. Enabling this option саn affect the interactivity of Live link updates.
