Unknown musical symbol

[ojkojbgoj]

Greetings all, I'm working on preparing a student of mine for his grade 6 ABRSM piano exam and have encountered a musical sign that I've never seen before myself. It's a tiny vertical line that is coming between two notes that have been connected by a curved line. In one instance the curved line is a slur and in the next it's a tied note - in either event, I'm out of depth in terms of understanding the impact of this vertical line. I've attached images of the instances in the music where this sign appears. Any clarification would be most helpful. Thanks in advance folks!

If I remember correctly, these are just ABRSM editorial markings, meaning the slur was not put in by the composer.
