The pdb generated by ambpdb doesn't have CONECT records, so the
display program is left to guess which bonds to draw. The only
use of such a pdb in the current case is to make sure the atom order
corresponds to your Gromacs trajectory. If it doesn't, you may need to
process your Gromacs trajectory to rearrange the coordinates before
analyzing in Amber.
