Relocate? Where.And it jumps back tp plugin’s folder

Hi,
I selected Individual (languages/loco/plugins/…) but I don’t know if this is correct. It jumped back to the plugin’s folder without my doing and it doesn’t let me change it back.
I didn’t find any hint where to place the translation update-safe. This is the only very complicated thing of LocoTranslate: I have to choose a location for my translation and every choice is wrong.
So what to choose that the translation isn’t destroyed anymore; so that it just works?

Thanks for your help.
