Can I build my own template?

[Deleted user]

I have been building projects using standard templates, but there are often elements of one project type that I want in the other project type. For example, I want to use the Document Approval template, But I would like to have the Backlog feature, as a choice too. Is there any way to include these elements, or is the only way to make a component project?

I suspect the disk being full has damaged some of your data.

Try running the integrity checker first - your issue is showing the usual symptom for an inconsistent set of data around the workflow, and the IC can find and fix that.
