All these errors are for hydrogen atoms. Likely, your pdb contains Hs that
do not conform to Amber naming expectations, which confuses leap. Maybe
removing all hydrogens from the pdb and having leap re-add them is the
easier way to go.

It very much depends on what those changes were to judge if the next is a
real problem or just a visualization issue. I would suggest trying just
without the hydrogens and see what leap then tells you.
