I must be missing something here. Taking a look at the logs you uploaded, the original broadcast date/time is being parsed from the filename.

The filename has 2019-10-20 and that’s what is also reflected in the dates. The Oct 19 in the Subtile isn’t a date but Text provided by TVDB (which is obviously incorrect but it’s coming from TVDB).
I’m not sure where you’re seeing the data being changed by MCEBuddy.
