If I complete a Repeating Task⁰ and then undo the completion, it creates a New Repeating Task¹ on the future date, and then actually completing the Repeating Task⁰ will create the future Repeating Task⁰. Undo twice and it creates a New Repeating Task², undo thrice and it creates New Completing Task³, etc. so on the next date I may see Repeating Task⁰ due as well as New Repeating Task¹, New Repeating Task², etc. And then if I don't delete the extras with correct options, I believe based on past experiences, that in two weeks I believe I will see Repeating Task⁰, New Repeating Task¹, New Repeating Task² all due again. So for practical example from today, Monday, December 8: ° I completed weekly task of 'Bring in Trash Cans', ° and then I Undid the completion. ° I then completed the weekly task 'Bring in Trash Cans' again + I now have two 'Bring in Trash Cans' tasks due next Monday, December 15th. ° Experimentally, I undid the 'Bring in Trash Cans' task completion today ° and then completed the weekly task 'Bring in Trash Cans' again + I now have three 'Bring in Trash Cans' tasks due Monday, December 15th. + Each new 'Bring in Trash Cans' task is scheduled to repeat weekly ° I delete all the extra 'Bring in Trash Cans' tasks due Monday, December 15th. ~ (but depending on which options I choose while deleting those extra tasks...) » Fast forward to Monday, December 22nd: I expect to see extra repeating tasks again. And this would continue every Monday until I delete them using the right options.
