One familiar title, separate shows
The catalog includes Love Island beginning in 2015, Love Island USA beginning in 2019 and Love Island Australia beginning in 2018. The original years help distinguish the series before you inspect their seasons. These are not three names for one shared episode list.
Keep the edition in the search
Try Love Island UK, Love Island USA or Love Island Australia. Open the card and compare the description and production details with the show you meant. If you remember a presenter, contestant or setting, use that as another clue rather than relying on the number of the season alone.
Save the checkpoint for that production
A checkpoint is attached to a particular series entry. Season 2 of one national edition is not season 2 of another. Save the last completed episode on the correct title page and update it manually after watching.
Open the three-edition collection to compare the entries. Check the viewing service's current seasons separately, since a catalog season record does not establish that every service offers every installment.
