I have a very irritating problem with one of my single pages, I created in a package.

It's page path name has a hyphen in it (e.g. " website/anything-something"). Everything is working until I'm in edit mode of this page. After saving, the first part before the hyphen and the hyphen itself is deleted by the system (so that I have "website/something") and I cannot enter the subpages of this single page until I change the page path directly in the database table to its name with hyphen again....

Does anyone have the same problem and a solution for this?
