Index out of bounds and divide by zero

I am receiving index out of bounds errors and a divide by zero error when running runI-TASSER.pl. Here is the command line and console output:

===============================================
time /media/sf_D_DRIVE/home/bill/I-TASSER5.1/I-TASSERmod/runI-TASSER.pl -libdir /media/sf_D_DRIVE/home/bill/ITLIB -seqname orf8 -datadir /home/bill/covid-19/orf8 -runstyle gnuparallel -java_home /home/bill/anaconda3

Your setting for running I-TASSER is:
-pkgdir = /media/sf_D_DRIVE/home/bill/I-TASSER5.1
-libdir = /media/sf_D_DRIVE/home/bill/ITLIB
-java_home = /home/bill/anaconda3

-nmodel = 5

The program runs to completion despite the errors. The sequence is identical to QHD43422 from https://zhanglab.ccmb.med.umich.edu/COVID-19/, but the predicted models are not similar.
