Kanban - Values change while switching Group

Hi all,

I have a Kanban chart. Each card has a priority. The priority should stay the same. However, when I move the card around, the priority changes to a random value.
Is this a bug, or do I miss anything?

I made a quick video:

Any help appreciated!

Sounds like you Kanban Save Order is writing to your priority column. Give the Save Order it’s own column.
