Todos disappear when moving between lists

Hey Martin, thank you for the new feature to move todos between lists. When I tried it, I noticed the following bug on Android and in the AppImage (have not tried further versions):

1. Schedule view: When I moved a todo from list A to list B the other todos of list A disappear. The todos appear again, when I open another view (for example the standard view of this library or another library) and then go back to the former schedule view.
2. List view: When I use the move-function in the list view (don't know, if this is the correct term; i hope you get it), all items of this list disappear. When I go back to the library overview the list says 'everything done' and there is no item left (this honestly made me a bit nervous...). They appear again, when i open another library and go back to the former library. In addition: When I move a todo from list A to list A (so it remains in the same list), this todo stays visible while the other todos disappear. They will appear again as described above.
