WFRP4e Help needed: Inline rolls not displaying when using the {template:wfrp}

I'm wondering if you can help? - I've been working on a few template based table automations, macros and some in-line rolls for my game in WFRP4e. I have the official sheet and compendium etc. Frustratingly if I write a macro script with the {template:defalut} on - they work perfectly, however whenever I change the template to {template:wfrp} the macro runs (and the animated dice roll) but when the box appears in the chat it doesn't display the results of  the dice rolled....  Can anyone help?  - (image shows the table roll, then the failed attempt to use the wfrp template and then then successful attempt to use the default.)  

for further info: I would expect the following script : &{template:wfrp}{{name=Fumble}}{{roll=[[1d100]]}}{{roll_name=Oops table}} {{roll_type=Critical fumble}} to deliver a D100 roll but when tested this simple script only returns this in the chat:
