The model predicted by I-TASSER is view differently by PyMOL

I am a new user and recently run for prediction of protein structure (job ID: S285827). My problem is that, the model predicted by I-TASSER was view differently in PyMOL where some of beta-strand structures at the C-terminal are missing. I can see clearly the beta-strands structure in the C-terminal in the 3D structure viewed in I-TASSER but not in PyMOL. I had also tried several viewing software such as Jmol, RasMol, Chimera and it seems that all of them gave the same structure that viewed in PyMOL.

It would be a great help if someone could suggest to me to overcome this problem.

Many thanks.
