Custom Fusion Transitions Don’t Trigger Render Cache

I made some custom fusion transitions to use on the edit page but they won’t render on User Mode like other fusion effects do... Did I do something wrong or is it expected?
I couldn’t find a way to force them to render either, cause there’s no option in the right click menu to render cache fusion output for a transition. So I’m not getting real time playback. Anyone know how to fix it?

The Transitions have their own Render Cache I think. Do you have "Automatically Cache Transitions In User Mode" selected in the Project Settings?

Ohhh that must be it!! Thanks
