How to (re-)create performance document

Worker has by accident deleted his Performance document. Although he is still eligible, he cannot re-create the document, it is not available in drop-down list.

The administration has similar problem:

using the Performance Document Eligibility form, we can search for the worker, see he is (forced) eligible for the document, but when we click on 'Add' the drop down does not show the document.

Any suggestion how to solve this and give the document to the worker again?
