NLU Data Convert JSON to yml

I have json data that looks like the following: nlu.json (17.4 KB)

then i run the following command in order to convert it into yml training format: rasa data convert nlu --data ./nlu.json --out ./data/nlu.yml

I get the following output file: nlu.yml (4.4 KB)

It skips the lookup examples, as well as the regex for price.

I would appreciate some guidance on what to do for best data conversion
