Start-IP can not be 0

Hey guys,

I'm facing an issue that I'm not sure if is my mistake or what, I hope you can give me an hand on this.

So I'm installing a new FG with version 7.2.6 using fortimanager and I'm getting a error that I didn't saw last time we installed a FG (was in version 7.0.x) also using fortimanager.

We use address objects and groups for the RFC1918 and now with it seems that we can't have the 0.0.0.0-9.255.255.255 range anymore since the FG says that "start-ip can not be 0", well sure let's change the address object, but I can't because "Could not change assigned objs"...

Well that object is part of a group, and that group is being used, but if I try to remove the group from the address object nothing happens, I mean, the group is still there.

I changed the IP on the global ADOM but didn't help.

So I'm left with a catch 22.

Can someone tell me what I'm doing wrong here?

EDIT: I forgot to mention that the address object is a global one, that's why I though updating the global one would fix this.

Best Regards
