Those should reply to new issue that has name Test Edge Wekan (version-number-here) at https://github.com/wekan/wekan/issues .
https://github.com/wekan/wekan/issues/2811
https://github.com/wekan/wekan/blob/main/CHANGELOG.md
Why? Well, Wekan has no undo yet. If you delete Swimlane/List/Card, it's gone. That's why it's harder to reach in submenu. It's better to Arhive those, and unarchive.

    #  dockerfile: Dockerfile
    #  args:
    #    - NODE_VERSION=${NODE_VERSION}
    #    - METEOR_RELEASE=${METEOR_RELEASE}
    #    - NPM_VERSION=${NPM_VERSION}
    #    - ARCHITECTURE=${ARCHITECTURE}
    #    - SRC_PATH=${SRC_PATH}
    #    - METEOR_EDGE=${METEOR_EDGE}
    #    - USE_EDGE=${USE_EDGE}
    #-------------------------------------------------------------------------------------
Uncomment from those this way:
    build:

      dockerfile: Dockerfile
      args:

        - ARCHITECTURE=${ARCHITECTURE}
        - SRC_PATH=${SRC_PATH}
        - METEOR_EDGE=${METEOR_EDGE}
        - USE_EDGE=${USE_EDGE}
Then start Wekan to http://localhost this way:
docker-compose up -d --build
