Task Lists show in Client but there is no 'List' tab in configuration-1525360302

Task Lists show in Client but there is no 'List' tab in configuration. (v6.12 on premises)

I'm not sure how these Task Lists were created as the end user has no Task Manager license. She did have a trial of Workflow Manager but it has since expired. Perhaps that is what allowed it?

She now wishes to delete the test file cabinet with which these lists are associated but the dependency prevents that.

Any clues appreciated

Steve,
Are they Tasks or Lists?  I think WFM also allows Lists to be created. You may need to put a temp WFM license back in to get at the Lists to remove them.
The easy way would simply be to simply remove the lists from the personal settings. Effectively hide them since they are just static lists at this time anyway.
