Tasks are duplicated in each kanban bucket

Hello, I really like Vikunja, but lately I’ve had the following problem

This is after creating tasks in the backlog and then looking around the system. On coming back to this projects kanban view (see image) shows all tasks in every bucket. Internally they share the database id (as seen in url) and if I delete one of them out of a bucket the will be deleted out of all buckets after a refresh. Moving around from bucket to bucket temporarily leads to duplicate items in the same bucket, but after a refresh I’m back to this image…
Interestingly it happens only in this project for the moment

Thank’s

There have been recent changes which should fix this. Can you verify if it works with the latest unstable build?

I updated and the bug has been fixed. Thanks.
