Backspace "misbehaving" in bash 5.1 while working fine in bash 4.2.53

Using Putty to access 2 different z/OS 2.4 images; Putty settings are same for each session save for the target IP address. On system with bash 4.2.53(2) backspace behavior works normally - content is deleted and cursor key backs up on screen to reflect that.  On system with bash 5.1.0(1) backspace deletes content from the buffer (but not the screen) and the cursor moves forward (sometimes more than a single character's worth).  On both systems using the native IBM supplied shell backspace works fine both before entering  bash and after exiting so the unexpected behavior seems to be pointing to bash 5.1.0(1).  Any pointers on where to look or what to change appreciated.  

Hi Karl,

Could you try to setup TERMINFO environment variable? It should contain a real path to share/terminfo folder that was installed with Bash 5.1:
export TERMINFO=<installation_path>/share/ebcdic/terminfo

Please, let me know if it solves the problem.

Thanks,
Sergey
