Importing flows. Drum problem

Hi
I have written two flows. I am trying to add the 2nd flow to the first. When I do everyting is great except for the drum part. I wrote it on a 5 line staff but it does not import that way. I tried the 2 different options for importing, add new playere etc. But I get the same result everytine.
Can I change the one I have imported, or should I delete it and reimport differently to gret the 5 line staff?

Thanks

Layout options>Player>Percussion… set drum kit to 5-line staff
