Failed to update snmp.v3

Global Settings >> Poller >> SNMP >> SNMP v3 Authentication (priority)

Add #1 - Okay
Add #2 - Okay
Add #3 - Will not accept Crypto password with more than 3 characters
Add #4 - I can click add it appears for a second and is then removed. If I click fast it will show a few on the screen but they are removed. It eventually kept #4 and allowed a 6 character Username and 2 characters for each password.

I can get them all in if I use “$config[‘snmp’][‘v3’][X]” but I was thinking the GUI was better for when I add multiple Pollers?

What logging do I need to track this issue?
