Opening page link will route to a empty page with wrong title at new 0.5.8 version

Hi Team

After I updated to 0.5.8 version, I find a bug as following which I never hit before.
I used macbook pro 2017, macos 12.0.1

I have a page block link as below

after I click this page link, then goto the empty page with wrong title.
I notice that the | is replaced by _

but I can find the page with correct title in graph

and I opened the page with correct title, all content are there

I don’t know why and re-index graph many times, many pages has the same issue.
