To-Do Deleted my Task Lists without permission.

[mbreslav]

I had 5-6 lists with a mix of completed and uncompleted tasks. When I selected a list and hit the triple dots on the top right of the app and selected 'Hide Completed Tasks' it proceeded to remove the entire list. 

I had 5-6 lists, now I only have one, the rest have vanished and there was never any warning or prompt indicating they would be deleted. Where have they gone? I wan't them back!

I'm running To Do Version 2.48 (210706.1158) on Mac OS  12.5.1.

If I login to the web app, the lists are there. The client however doesn't show them.

I ended up removing 2.48 and am trying 2.78. 2.78 shows the lists and appears to work as intended.
