I have a single tag that I cannot delete. Toodledo said that I had a hidden task with the tag and I removed the tag by unhiding the task but the tag is still listed under Tags in the main menu. Again Toodledo says that there are hidden tasks but when I remove the filter there are no items to be seen. The tag is in Japanese if that makes any difference. I am not at all experienced with Toodledo and have not used tags before so it may have nothing to do with the language. I only have this one tag.
