WebEPG Some channels not displayed correctly (1 Viewer)

[hassegubben]

I have the exact same problem for one channel only. I am only using WebEPG right now. I used XMLTV previously, but stopped when the swedish grabber stopped working. WebEPG works very well for all my 15 channels but one has the above mentioned problem. I think I have read somewhere that "Delete old files before import" should be ideally checked. If RoMan_P's suggestion fixes my problem I will un-check this checkbox. What will the downsides be?
