I feel like a moron for asking this, but...

... how do I delete shows from my list of series links? I have a whole slew of shows on my Prioritizer that are cancelled or that I no longer watch, but I can't seem to find a way to delete them. I know I used to be able to, but I've either lost too many brain cells since then, or something else has happened. Any guidance you could provice would be most helpful.

Highlight them, then use the "-" dash key lower left button of number keypad and press it twice, dash dash...

Another answer is to wait for the national roll out of 18a.
With the new version it has the option to delete highlighted shows with the red(delete) button. 18a should be rolling out this weekend.

Also, for the red button delete, there will be a hint right on the prioritizer screen. No more fumbling through your brain cells trying to remember the correct sequence. :)
