Error "Can't be released: ManualReviewPending"

I am building gimp-simosx on the build servers and I am trying to release it to the edge channel.
I get the error Can't be released: ManualReviewPending. It is not clear how to proceed from there.

The GIMP snap package does not have the Qt5 libraries, therefore it is not possible to add plugins that require those libraries. With my change, I am adding this with the aim to check whether the plugin will end up working.

    interface: content
    target: $SNAP/qt551
    default-provider: qt551
