Unable to remove trigger from master slide (SL360)

Hi,

I have a Storyline 360 issue which is beginning to annoy me.

While going through a Storyline file which had been created by someone else, I noticed a slide (final one in a scene) which had two triggers associated with the Next button. The trigger reads:

When the user clicks or swipes next

• Jump to slide next slide
• Jump to scene next scene

Obviously, you don't need both, so I tried to remove the "Jump to slide next slide" trigger, as this was the final slide in this scene. However, the "Delete the selected trigger" button is greyed out (as is the "Edit the selected trigger" button). They're both available on the "Jump to scene next scene" trigger.

I then had a look at the master slide, and found the trigger there (I've attached a screenshot for reference). It is on the Master and on the associated layout, but I am unable to remove it from here either. The master is not preserved or locked in any way that I can see, so i'm at a loss to know how to remove it now.

I know that I am able to disable the trigger so it is ineffective, but I'd rather remove it altogether as it is superflous.

Any suggestions?

I am using Storyline 360, latest update, July 27th, v3.54.25674.0 on a Win10 PC.
