Missing drum instruments after XML import

After importing a xml file from Finale to Dorico some drum instruments have vanished.
Closed Hi Hat, Snare Drum, Rim Shot, Toms 1 - 2 - 3 and Ride Bell Cymbal have been well converted but Bass drum and Ride Cymbal are missing.
In Finale I used a Percussion Table.
Any idea what happened?

We would need to see the MusicXML file to be able to say what might have happened. Could you please make a copy of your Finale file, remove all of the other instruments, delete all but a few bars, then export the MusicXML file from that reduced Finale file, and attach it here in a zip file so we can take a look?

I just have send the xml file of the drum part to your e-mail adress.
Thanks for looking.
