You can create a new tag with correct spelling, tag with it all tasks that were tagged with the bad spelling tag. Then you can remove bad spelling tag from all tasks, that would remove the misspelled tag. That sounds more complicated then it is . You can use search function to find all tasks with the misspelled tag and then select them all and use “add tag” and 0remove tag” for all of them. Hope that helps.
Please, try to restart Beorg. And check again. Thanks.
You are welcome!
This will become slightly easier in the next update with the introduction of bulk editing.
Regarding a misspelled tag - beorg keeps a cache of tag names in memory which it uses to provide suggestions, this is reset if beorg is restarted.
