At least 3 different possible editors may have been used, default 
appears to be eve with an eve keypad layout that does not match the 
labeling of any VT-xxx keyboard that I have ever seen.  EVE has multiple 
optional personalities.

I use EVE with the EDT keypad and a bunch of custom settings.

The backspace character is Control-h.  Putty will also by default send 
it when you press "shift-backspace".

The behavior of an editor to the backspace code is dependent on the editor.

Your pictures show that you have the default settings.

I would not put a /perm a set term command in a login.com.  And /perm 
will not save what /inquire discovers.

I do not have a serial connection with Putty and I can not reproduce 
your issue on VMS 8.4.

The last time I tried to use putty on a serial port was at least a 
decade ago and putty crashed with a segfault on every attempt to do so.

I have not seen any issues with VT escape handling in Putty with editing 
files or other VMS utilities.

Since set term/inquire seems to have fixed the issue, I suspect that the 
terminal size/type set on VMS was different than what was set in Putty.
