In a questionnaire with evaluation, I entered evaluation rules of the following type:
{if (((P23.value == "0") and ((P02.NAOK == "Y") and (P09.NAOK == "N"))), "You could take advantage etc ..." , "")}
My problem is that all the entered rules are displayed, in code, whatever the declarative done.

Everything worked perfectly on a version of lime survey prior to 3-15-5-build-181115;
the update to 3.17.15 + 190903 did not change the problem.
To be clear, I installed LS locally, imported my questionnaire: same observation.
