Why doesn't this regex take effect?

When I remove a word, it takes effect. Is there a word limit, or is it the reason?

I didn't do anything, just set "内补模型条件" > "内补模型条" and it worked

I found that it seems that in Chinese, directly using the original name of the node does not work. Some node names must be deleted or modified. in order to be able to match normally.
