These two variables are missing from the codebook. We have normally no way of knowing whether the variable is numeric (in this case, we can check other cycles), but it's probably better to keep such variables numeric by default.
Other examples (not exhaustive) are HPVSWR_F, OHXPRL_B, OHXPRU_B
This came up as one source of mismatch in the R vs DB translations.
