regex are not working very good

[danmihaila]

We are trying to use the redact-pii which is working good, but when doing some checks on files I am finding some strange results:
1.
original data:
yes,hiraan,belet_weyne,no,RE-HRN-BTW-13,male,age41_59,eldery_male,eldery_male,14,no,0.250750683890174
data after redact-pii applied:
yes,hiraan,belet_weyne,no,RE-HRN-BTW-13,male,age41_59,eldery_male,eldery_male,14,no,0.CREDIT_CARD_NUMBER

removing the credit card number rule, it founds something else:
2.
original data:
yes,hiraan,belet_weyne,no,RE-HRN-BTW-13,male,age41_59,eldery_male,eldery_male,14,no,0.250750683890174
data after redact-pii applied:
yes,hiraan,belet_weyne,no,RE-HRN-BTW-13,male,age41_59,eldery_male,eldery_male,14,no,PHONE_NUMBER90174

Any hints?
