Import bookmarklet is showing Japanese but importing into English. This happens the second and subsequent times I imported from this page. A workaround is to open the dropdown menu and REselect Japanese even though it is automatically selected.
Happened importing various paragraphs from this page: 石原慎太郎 - Wikipedia
This has just started happening to me as well, but I wasn’t sure if it was my browser saving the last option, like it does on some webforms. I’m kind of glad it isn’t just me.
