Wiki pages dissapearing

Summary

It is happening that when creating wiki pages by [[wiki-page]] the page which is created disappears, the created link doesn't point to it any more.

Steps to reproduce

Create a page with [[wiki-page]], click on the link to it, edit the wiki, and save. Go back to the previous page and click the wiki's link, all the written info would be lost. However, the wiki still exists, I managed to find it. I is just that the link doesn't point to it, so I had to use [wiki](wiki-link) in order to achieve the same results.
