Double hairpin when condensing


I m trying to understand what I am doing wrong.

When condensing a cello part I get the hairpin doubled up. Anyone might know which mistake I might have done?

They are both linked to the correct stave when non condensed.

I would double-check that there isn’t another hairpin hiding underneath your >mp group on the top cello staff. Perhaps the easiest thing is to delete the dynamics from one or both staves, then re-input it on one, then duplicate to the other. Dynamics have to be exactly the same (including whether they’re grouped or not) on all staves in a condensed group in order to appear just once.
