[Persian][Numeral] Extract incorrect number from text

[AmirMohamadBabaee]

when I checked the numeral dimension, I figured out that there is an issue with the numeral extractor.
in Persian, صدرا is a first name, and صد means hundred. when the name is fed into the Duckling the output is 100را which is not correct. I tried some other examples and found it in another example when the verb بده (which means give) is converted to ب10 cause ده means ten in Persian.
How can I change the configuration of Duckling to enforce rules to apply just to tokens that are space separated?
