MusicXML file exported by Tux Guitar causes error when importing to Musescore 3
I was playing around with Tux Guitar because of it's Guitar Pro 7 importing capabilities. But it seems that if I use Tux Guitar to export a file to Music XML, this file then cannot be read properly by Musescore and causes an error. I've tried this file on the most recent Appimage (3.1) on Manjaro Linux and the error I get is:
Fatal erreur : ligne 10 colonne 26 Element creator is not defined in this scope.
My question is then, is Tux Guitar exporting an invalid Music XML file or is there something wrong with the import capabilities of Musescore?
I've attached the exported file as an example.
