It isn't really a rendering issue, but a bonding issue (or an atom-ordering
issue -- the structures in this multi-model file do not have the same atoms
in the same order). You need to load the structures in this multi-model file
with the discrete flag turned on. This will force PyMOL to construct a
bonding-table for each model separately.

load top4fix.pdbqt, discrete=1

Cheers,
Rob
