When an actor is selected Infuse displays TV series with “x Seasons” under the series to show how many season that actor is in.
However I have found a few which instead display individuals seasons. For example:
Actor: Michael Weatherly
Series: Bull (5 Seasons), NCIS (each individual season displayed)
Actor: David Boreanaz
Series: Angel(5 Seasons), Buffy the Vampire Slayer (each individual season displayed)
