ServerWMC Guide Data

I’m running Kodi on a few Nvidia Shield boxes with ServerWMC running on my old WMC box and it’s all working great, however after a day or two guide data starts becoming sparse and it’s like half my guide is missing data. Exiting Kodi and going back in fixes it and all missing guide data is refreshed and reappears, I’ve set it to refresh data every 15 mins why do I need to exit and reopen Kodi for this guide data to show up after a couple of days? The longer I leave it the more guide data starts missing. Is there a fix for this so I don’t have to exit/reopen Kodi all the time?
