Problem link W/O slash

[truefriend-cz]

Hi, when browsing folders, it happens that when browsing subfolders at the top of the navigation, the path is displayed without a leading slash. When I click on any of the paths I click, the okdaz appears with a leading slash.
Is it possible to unify the display of the folder shape?

Example:
Link on folder is "dir=Folder".
Link in dir_nav_links is: "dir=/Folder"

The latest version of index.php does not use leading '/'.

Unfortunately, although I am a programmer, I am in a human environment where I am prohibited, blocked from programming, editing and developing other new scripts. The local state police is completely useless because they don't consider it a thing for making money or any operational needs of a person. There are legalized forms of murder in my area where some members of the state police are also used. This has been happening for about nine years and has no restrictions or stops. Whether I'm dealing with other members of the police or government prosecutors, etc. I'm trying my best, but I have more work to do so than to be able to work on the development or editing of scripts, not only in PHP. I apologize for the longer post. And a mention of the problem. Maybe in time it will be better if I live to see it.
