Right now I only test with a small xml file from here https://lumi-radio.dk/test/1mos.xml - it came in as Genesis, we call it "Første Mosebog".
I have fund a workaround - Click on "Edit bible" an select "Program language" - then the names are displayed in som sort og correctly. - it is not the name from the file, but from OpenLP I think.
But in this I fund a other strange error - in this xml where are used som linebreak - OpenLP cannot handle these, so the whole verse does not come in view - see chapter 3 verse 15 for example. Only the first sentence comes with.
