[AMBER] problem w/ radial results

I have an explicit solvent simulation with 0.2 M salt. I am calculating the
gofr of Cl- ions around the protein with the following command in ptraj:

radial distCl 0.05 10 :Cl- :1-93 closest

I am having results that do not make sense, the ions start to line up at
around 0.175 A which is considerably lower than a H--Cl bond length. I
checked the energy values to see if the atoms somehow clash, I found
nothing indicative of that kind. I checked the trajectory in VMD, nothing
looks like .175 A close.

How can I fix that issue?

Best,
