When using a customized field configuration for a specific issue type, an Advanced Roadmaps required field may be hidden, causing the plan to not show more issues from this issue type.

If a new issue is created in the plan using the affected issue type, when you "Review changes" and "Save selected changes" In Jira you encounter the following error:

Error
This issue is missing some details that are specified in the issue sources of your plan. To make this issue visible, add these missing details to the issue.

It would be useful if the message showed which is the missing details.
