Formula used for converting between altitudes in WGS84 and AMSL is incorrect.
We are using a derivation of this library: https://github.com/matthiaszimmermann/EGM96
Refer to this https://vdatum.noaa.gov/docs/datums.html for the forumlas.
We have forked the EGM96 repo, fixed the README, and submitted a merge request.
