The Protel pad cannot be set as a pass hole

Today, I encountered a strange problem. I wanted to place a positioning hole on the PCB, but I found that after calling the pad placement command, it was a surface pad without a through hole.

It's strange, isn't it because the software settings of dxp are accidentally changed, or is it because of the limitations of PCB design rule settings?

I said something happened to Baidu, but Baidu couldn't find the answer.

I think it is still possible that there may be a problem with the pad settings, so I made a mess in the pad attributes.

The problem is found. It turns out that the layer must be set to multi-layer to achieve multi-layer effect. You can set the pad to the through hole form.
