WHZ expanded WHO excel lookup table for boys 2 to 5 years

Here in Nepal we are programming our CommCare electronic forms to lookup z-score values for weight-for-length/height so that we can refer survey respondents to a health facility for treatment of SAM or MAM according to their WLZ or WHZ.

On the WHO website: https://www.who.int/tools/child-growth-standards/standards/weight-for-length-height we found the "Expanded tables for constructing national health cards" that go up in increments of 0.1cm to use for lookup. The problem is that in the place where the z-score table called "Boys z-scores: expanded-tables (Weight-for-height).xlsx" should be we find the percentile table instead. This is clearly a mistake in the uploading of lookup tables on the WHO website. Has anybody managed to source this expanded table of z-scores? If so please could you share?

Many thanks Naomi Saville
