Double Bar with Grace Notes Problem

I have a lot of concert/marching band music some of which is old hand written manuscript. From time-to-time I try to transcribe the hand-written manuscript to a much more readable product.

Generally I do each instrument then combine them into a score.

The problem is, in this case as shown in the sample below and attached image, that a double bar before the grace notes, on the clarinet 1 and 2 seems to cause a separate bar line, which also increments the measure counter, but only on the score.

Below is an extraction as a two staff script (the same as when each independent part is combined into a score). Each part needs to have the same bar markings so I can’t just leave the double bar out on a couple of parts.

In this case I just took the double bars out completely from all the parts but I am still wondering if it is my ignorance or what seems to me to be a bug.

In the attached script, by commenting out the double bar in the clarinet2 staff the problem goes away on the conductor’s score but of course now the clarinet2 part has a missing double bar.

I tried creating a variable defined as: dblbar= { \bar “||” } then on the conductor score defined it as: dlbar = {} for all but the top line of the conductor’s score in this case the flute. I believe it might work but made management more difficult for something that I figured I was doing wrong.

Any thoughts?
