Random Infuse empty catalog

I’m with and AppleTv 2 (OS 5.3) and ATV (Black) 2.6

I just just restored AppleTv 2 (OS 5.3) and ATV (Black) 2.6 because a problem with netflix but now I’m suffering with a problem with Infuse catalog.

The AT2 is connected with my Qnap NAS and in the initial setup works fine… all my movies and series are loaded with correct metadata BUT overnight something happen and the entire catalog disappears!!!

If I force a refresh, Infuse load again the data and everythings goes back to normal!

I’m going crazy… This happen even with wifi or ethernet cable but doesn’t seam to be a NAS/Network related problem.
Any idea to solve or understand what happen during the night?

Thank you in advance.
