I hope they weren't all three in AUCTeX ;-)

The behavior you described (adding entries to `TeX-command-list') is expected.

The problem was that the "BibTeX" and "Index" entries are changed in
tex-jp.el, but this done without checking whether they were actually
there, resulting in the error you spotted.  I guess that not many
users *remove* entries from `TeX-command-list', that's why probably
this bug went unnoticed for years.  Anyway, that should be fixed now
on git, thanks for reporting it.

To be honest, changing the value of that variable with customize is a
bit tricky, because you will miss future changes or new entries made
to the default value of that variable (and this was probably the
source of your problem).  The best way would be to only *add* custom
entries (for example with `add-to-list').

Bye,
