I kindly ask for confirmation that these are general issue (and not an issue of our current WeKan environment):

Setup:

Two boards, a project board and a task board. The project board has sub-task enabled. Sub-task are supposed to be created on the task board.

Behaviour:
Whenever a Sub-Task is created, this goes into a standard-column ("Warteschlange" / probably "cue" in English) in the predefined board for subtasks. Unfortunately, creating sub-tasks from different cards create new "Warteschlange" columns > thus, we need to clean up columns everytime Sub-Tasks were created.

I can reproduce this behaviour even in a newly setup board.

Also, whenever I go the other direction (creating a card on the task board and then try to link it to a card on the project board) I always need to refresh the card before I am able to lookup cards from the selected boards (otherwise it allows me to select a board, but shows no items)

Hopefully someone can help?
