When running AQM, it only couples to ATM and ATM doesn't couple to Ocean or Ice model. I would suggest to make it simple by changing the code to:
if (cplaqm .and. .not. cplflx) then
do i = 1, im
dtsfci_cpl(i) = dtsfc1(i)*hffac(i)
dqsfci_cpl(i) = dqsfc1(i)
end do
end if

I would prefer to leave in place the ability to use AQM in fully coupled mode for future applications.

do i = 1, im
if (oceanfrac(i) > zero) then
if (.not.cplflx) then
dtsfci_cpl(i) = dtsfc1(i)*hffac(i)
dqsfci_cpl(i) = dqsfc1(i)
endif
endif ! Ocean only, NO LAKES
enddo
end if
else ! heat fluxes are required over land
dtsfci_cpl(i) = dtsfc1(i)*hffac(i)
dqsfci_cpl(i) = dqsfc1(i)
end if
end do
end if
