Manage Path Replacement???

[KodiUser1138]

I just set-up my JF server wit ha reverse proxy and in the process my home IP changed. I now need to update all my Kodi instalations to the new server destination. There's been issues recently that once setting up JF in Kodi I have not been able to go back to add new or refresh/repair JF libraries and had to completely kill my movies database and start with a fresh new scan from JF.

Now I am attemtping to do that while using Native mode for my home media systems because using direct paths is far easier (and helps with other aspects of Kodi) than the add-on. Once I confirm my SAMBA is working I go to a screen I've never seen before, Manage Path Replacement, and the 2 options don't seem to do anything. I have no idea what these are for and if I select Finish nothing happens with my library. There is no scren to select libraries and Kodi does not scan anything from JF.

Then going ito the add-on to try and refresh libraries I only have the option fo ALL  ( which I don't realyl want) but that still does nothing. So now my Kodi has no media library.

I am lost to understand what is now going on.

*** Now atempting to use Add-on mode on a local machine and I get the same results. I previously got this to work on my laptop which I do want in add-on because I use it remotely to access my server. It is set up, minus the ability to make any future changes/repairs.
