完全相同的主机ID不匹配

我在64位Linux系统上更改了我的主板和我的MAC地址。
我尝试使用产品许可Web界面更新节点信息，但它经常说该主机有一个许可文件，我必须在编辑或删除该主机之前将其删除，即使我删除了该Web界面上的所有许可证。
因此，我创建了一个具有相同名称但具有新MAC地址的新节点，并成功生成了我通过邮件收到的新许可证文件。
但在我安装之后，Xilinx配置许可证管理器仍在“主机ID匹配”列中显示“否”，但“主机ID”列与网络接口卡ID完全匹配，如附图所示。
请帮助找出完全相同的主机ID不匹配的原因。

I have changed my motherboard and so my MAC address on a 64-bits Linux system. I tried to update the node information using the Product Licensing web interface but it constantly say that there is a license file for that host and that I must delete it before editing or deleting this host, even after I deleted all my licenses on that web interfaces. So I created a new node with the same name but with the new MAC address and successfully generated a new license file that I received by mail. But after I installed it, the Xilinx Configuration License Manager still say "No" in the "Host Id Matches" column, but the "Host Id" column matches exactly the Network Interface Card ID, as you can see in the attached picture. Please help to find why exact same host id don't match.
