The Swisscom TV programme guide has had an error for a very long time. Where it shows "TheTonight Show with Jimmy Fallon" which is broadcast Monday through Friday at 2330 (and several times on Saturday and Sunday), the actual programme that appears at these time slots is "Late Night with Seth Myers". This problem dates back several years if not mistaken.
I found the following thread in German that describes the same problem.

One reply says this problem is because Swisscom shows the CNBC UK version but the programme guide is from the CNBC Europe version. The CNBC UK channel replaced "The Tonight Show with Jimmy Fallon" with "Late Night with Seth Myers" in November 2016. Apparently the CNBC Europe version still shows "The Tonight Show with Jimmy Fallon."
Could you please investigate this problem with the source of your EPG data and try to get the correct CNBC UK EPG data.
I ound the following CNBC press release dated 1 November 2016 advising that their UK channel was making the change mentioned above. I think the Swisscom EPG has had this error since then.
Thank you.
