Tvheadend

Hello, I have install on my synology tvheadend with a sony playtv tuner. Everything works great, channels, epg. The problem is that every time I program a recording when it finish that recording I can not access any more to see channels or administration until I stop service and then restart it again. It is annoying problem. Any suggestion about why is happening. I have try to set the recording from the android app, or from kodi, or even from explorer in administration menu.
