Comment 0 for bug 1811275

Previous kicad version allow chars like slash ('/') in symbol name. After some upgrade all such chars was deprecated and silently(!) replaced with underscore in library files. Seems like remap procedure on opening old schematics replaces slash by underscore but unable to find translated name in libraries and creates , although symbol with translated name exist in library. Example: symbol 74HC595/SO in old schematics remaps to project_name-rescue:74HC595_SO while 74HC595_SO exist in library.
