Issue Summary

When using the single work item move option to change from one work type to another, the message presented mentions the retain options.

However, no retain checkbox appears when moving issue and using the MoveIssueUpdateFields!default.jspa modal.

Message is:

Your destination's 'Epic' issues may have different field settings than your source project. Update the values for fields in these issues, or select Retain to keep the field's current value.
Component or Version field data is permanently lost, if you move issues between projects. Other incompatible fields will appear empty, even if you choose to retain their values.

Retain checkbox appears only with Bulk move option - bulkedit/BulkMigrateSetFields!default.jspa

Steps to Reproduce

1. Open a work item from CMP.
2. Click to move the work item to new work type.
3. MoveIssueUpdateFields!default.jspa modal appears.

Expected Results

Either update the message to reflect the feature's way work or add the retain option, as the message suggests.

Actual Results

No Retain option appears.

Workaround

Use Bulk move option even if it's for a single issue. 

Please note that there are other constraints that can affect the Retain checkbox - like the context of the custom field so other scenarios exist where the Retain checkbox might not appear.
