That bug is indeed fixed in version 16 (and I recommend upgrading).
However, your problem does not appear to be the same one.

In both cases you're specifying 'first', which means use the first
frame read in as the reference structure. You need to specify
'reference' or 'ref <refname>' etc. if you want to use a specific
reference structure. See the manual for full details.

Yes, that is what the 'rms' command does by default unless 'nofit' or
'nomod' is specified.
Hope this helps,
