That's not how series link works.
When a series is being shown, the broadcaster transmits two IDs as part of the EPG for each episode. One ID relates to the series and the other to the episode. Thus when you ask TVH to record a series, it schedules recordings for all broadcasts having the same series ID.
If the broadcaster repeats the series, eg the following day at a different time, then each of those episodes will have the same episode ID as the first showing but a different series ID.
The broadcaster will probably add 'New:' to the title of the first showing but not the second, however this doesn't matter to TVH which is only looking at the IDs.
