High number Episode-num Ziggogo.tv for programmes without episode data

[BernoldNL]

Describe your issue

With Ziggogo.tv I'm getting quite a lot of crazy high episode-num numbers for series that do not seem to have a season/episode number in the guide it's grabbed from.

As an example:

<programme start="20260108210000 +0000" stop="20260108214000 +0000" channel="BBCNL.nl@HD"><title lang="nl">Ghost Stories</title><sub-title lang="nl">The Room in the Tower</sub-title><desc lang="nl">Mark Gatiss, meester van het macabere, presenteert kille kerstverhalen voor de koude winteravond.</desc><credits><director>Mark Gatiss</director><actor>Tobias Menzies</actor><actor>Joanna Lumley</actor><actor>Ben Mansfield</actor><actor>Polly Walker</actor><producer>Mark Gatiss</producer><producer>Isibeal Ballance</producer></credits><date>20250101</date><category lang="nl">Dramaseries</category><category lang="nl">Horror</category><country lang="nl">GB</country><episode-num system="xmltv_ns">13419999.2025122406.0/1</episode-num><episode-num system="onscreen">S13420000E2025122407</episode-num></programme>

Same programme on https://www.ziggogo.tv/nl/epg/initial:

Note that this programme does not seem to have episode information.
