Thumbgen Help?

Been having a bit of a mare with Thumbgen and the TV series side.

Sometimes it needs a folder called Season 1, sometimes not, and some it has the Season on TVdb, but it still does not work…

Anyway, my main bug bear is Seasons of 20 odd episodes, and I want to use the Episode Screencap as the image on the sheet, but if you do it in automatic it selects random fan arts.

Am I missing a tweak when I get it to select the first picture in Thumbgem automatically (which always is the screencap), or is that the way it is…?

Perhaps you will be able to receive additional assistance from ThumbGen Support.
