Configs "RealVNC" or "fmwp" have been added without noticing. Why?

Configs "RealVNC" or "fmwp" have been added without noticing. Such as..

“RealVNC-Other”, “RealVNC-Web”, “RealVNC-ICMP”, and so on.

“config rule fmwp FortiOS.SSL-VPN.Enc.Buffer.Overflow”, “config rule fmwp FortiOS.SSL.VPN.Custom.Information.Disclosure”.

Why did this happen?
