IPv4 addresses from FORTIGATE appearing completely wrong in WebUI

There is an issue with the FORTIGATE poller.

"IPv4 addresses" are completely wrong.

IP addresses are changed, ommitting the 1st octet and adding ".1" at the end (see capture).

If you have an interface "192.168.1.1/24" configured, it will show as "168.1.1.1/24", which is completely weird!

Could you help me on this?

Thanks!
