[QE-users] Missing Hubbard atoms from ATOMIC_POSITIONS card

Dear all,
The following must be an easy fix. I just started to use hp.x for LiMnO2
(hypothetical structure), which is a magnetic (AFM) insulator. I followed
the example02 of the HP code (NiO U parameter) and it worked as expected. I
do the same sequence for the above structure (i.e., magnetic metal,
magnetic insulator, linear response), but at the last step, hp.x stops with
the following error:
" WARNING! All Hubbard atoms must be listed first in the
ATOMIC_POSITIONS card of PWscf
Stopping..."
Any hint to show me what I'm doing wrong is highly appreciated.
I'm using QE 6.4.1
Input for the second step (magnetic insulator) is pasted below:
