In a woodwind quintet, I want to add a repeat sign to 2 instruments, French Horn and Bassoon. It inserted properly on the Bassoon, but wouldn’t take on the French Horn. From looking at the staves above the repeat sign, it seems the problem is that the French Horn and Clarinet are somehow connected.
You see that at the end of piece too.

How can I “unconnect” the Clarinet and French Horn, so that I can normally insert the repeat sign on the French Horn?
