How to Remove Greyed‑Out Pitch Bend Data Without Handles

[prko]

Hello,

I have created an ossia staff, but it contains redundant pitch‑bend data that I would like to delete.
However, I cannot find any way to remove it.

I am attaching the project and a screenshot.
Could anyone advise me on how to resolve this?

This seems to work…

In Write mode, select the ossia rest in bar 10.
Then Play>Automation>Delete All Automation for Selection
