Hi. I realise the episode names are displayed in episodes, not sure you understood what I meant. So taking it from step 1 on an iPad to try and explain, I found out why it was doing what it does:
Open Infuse
Open TV Shows favourite
Select show - in this case 24
Show opens with a banner at the top and the seasons displayed underneath
In the banner it displays 24 - Season 1
I thought that was an error and that it should just be 24. I didn’t realise however that you can swipe between the banners for the different seasons 
Is this specific to the iPad or does the iPhone do it too, the iPhone just lists the season tiles with no banner so wondering if it’s iPad specific behaviour or a setting I’ve missed on the iPhone. Thanks for the fast response.
