Removing TAB from chart?

Hello-- I've downloaded a drum part from Songsterr, opened it in Guitar Pro (trial), saved as Music XML, then imported into Dorico.. the notes were all doubled, so on the Dorico forums, they suggested importing into MuseScore to see if I might be able to tell what is going on. It appears that the notes are all duplicated in the TAB. (See attached image)
Is there a quick/easy way to remove the TAB in MuseScore.. so that hopefully, if I were to re-export MusicXML and import into Dorico, I wouldn't end up w/ the doubled notes?

Thanks!
