I'm getting this error message when creating a cetain issue type called "Todo".
I've analyzed the issue type to find any difference to other issue types that are working as they should, but at this point im clueless of whats wrong.
Sub-tasks are defined in an own issue type, the sub-task issue type are on -1 in the issue hierarchy. "Sub-task" issue type are configured as an subtask type of issue in the config.
Todo issue are on level 0.
Both issue types are configured in the issue type scheme used in the project.
Any ideas of where to look next??
