Meta Tag Issue

Following problem I have: the first use of Infuse Pto on my ATV4, the meta tags was assigned to my movies. Later, there were problems with network shares. I deleted the network shares and added them again. Infuse tried to sort the Meta Tags again. When I found wrong meta tags I tried to edit the tags, but the search engine doesn’t work.
Below the movie I can read the old Titel of the movie.

What can I do to edit the meta Tags?
