Unable to delete dynamic (v4)

When moving dynamics around, some hidden dynamics are doubled.
I’m sometimes unable to delete those.

Bug. Any solution? v4. Fixed in v5?

Attaching a Dorico file (or portion thereof) that illustrates the problem will help people explore the problem you cite.

I have this problem sometimes. What works by me is use cut instead of delete. And then never paste.


Trying to make a cut-down version. But when trimming other content, the issue disappears.
