'Automatically-added' page name to the link causes troubles

[Zengzhi_Zhao]

Hi

Put it simple, in my confluence page with the name Pagename, I add a link with Heading named Headingname in this page. So I think the correct link should be #Headingname.

However, in the occasional updates of this page, the link turned to Pagename#Headingname and when I clicked this link it jumped right to the loading edit page which will never finish loading.

All I did when updating the page was modify the page content and add/delete/modify some links. I don't know this 'automatically-added' page name is caused by the system or my operation. Please help me.

Thank you
