Without show some error message, you can add a rule using invert option with
flags, but after, you can not show the table. Here some examples of this bug.

 $ sudo nft add rule ip test3 input ip tos and 0x04 == 0x02 counter accept
 $ sudo nft list table test3
table ip test3 {
    chain input {
         ip tos & 4 == 2 counter packets 0 bytes 0 accept
    }
}

[Here, all is ok]

 $ sudo nft add rule ip test3 input ip tos and 0x04 != 0x02 counter accept
 $ sudo nft list table test3

[ERROR: The table is not shown]
